Cardiac arrhythmias are common in hospitalized patients, with their incidence increasing in older patients and those with comorbidities. Cardiac arrhythmias represent a trigger for approximately 10% of rapid response team (RRT) activations. Of those, atrial fibrillation (AF) is the most commonly observed. Other common cardiac arrhythmias in the in-hospital setting include supraventricular tachycardia, atrial flutter, ventricular tachycardia, and bradycardias. Members of the RRT should be skilled in the diagnosis and management of these common arrhythmias. This chapter presents an overview of cardiac arrhythmias that RRT members are likely to encounter, discussing their incidence and significance, as well as their immediate management.

The purpose of this chapter is to familiarize the reader with the typical fluoroscopic views and electrograms used throughout this book. First, the rationale for the particular views used and the standard electrogram display format are introduced. The discussion then continues to the important fluoroscopic landmarks relevant to the arrhythmias encountered in the electrophysiology laboratory. These landmarks are discussed in the context of the electrograms obtained from mapping these sites and their importance from an anatomic and ablation standpoint. The first topics are the common fluoroscopic and anatomic principles relevant to the electrophysiology laboratory; then the specific differences in catheter use and electrograms obtained from the standard fluoroscopic catheter position in supraventricular tachycardia, atrial flutter, atrial fibrillation, and ventricular tachycardia; and finally some unusual positions and congenital variants.

Background/Aim. Numerous trials have shown a high success of radiofrequency ablation (RFA) in the treatment of the patients with cardiac arrhythmias. We aimed to examine the RFA initial success in treatment of different cardiac arrhythmias and the RFA success after 6 months of followup. Second aim was to evaluate influence of all clinical and echocardiography parameters on initial and 6-month success and failure of RFA. Methods. The present study included 320 consecutive patients with atrial and ventricular arrhythmias in which RFA was performed during 2014 in the Institute for Cardiovascular Diseases ?Dedinje?, Belgrade, Serbia. We evaluated the initial RFA success and success of this procedure after 6-month follow-up. We also investigated the prognostic role of clinical and echocardiography parameters on initial and 6-month success and failure of RFA. Results. The RFA initial success for RFA of atrioventriculas (AV) node and AV nodal reentrant tachycardia (AVNRT) was 100%, RFA of pulmonary veins 99%, RFA of atrial flutter 92%, RFA of premature ventricular complexes (PVC) and the Wolf-Parkinson-White (WPW) syndrome 87%, RFA of ventricular tachycardia 85% and RFA of atrial tachycardia 78%. The success of RFA after 6 months of follow-up for RFA of the AV node was 100%, RFA of AVNRT 94%, RFA of atrial flutter 90%, RFA of WPW syndrome 86%, RFA of pulmonary veins 79% (paroxysmal atrial fibrillation 88% and persistent atrial fibrillation 63% with a significant difference p < 0.05), RFA of PVC 78%, RFA of ventricular tachycardia 77% and RFA of atrial tachycardia 67%. Conclusion. This study proved a very high RFA initial success in treatment of cardiac arrhythmias and a satisfactory RFA success after 6 months of follow-up. Only the prognostic value had the type of atrial fibrillation in the group with catheter ablated pulmonary veins: after 6-month follow-up, the patients with paroxysmal atrial fibrillation had a significantly better outcome than those with persistent form.

Background: Artifact waves in the ECG and Holter recording are not rare in clinical practice and can be mistaken for tachyarrhythmia. Objective: To orient the practicing physicians to differentiate these artifacts from cardiac arrhythmias. Patients and Methods: Thirteen patients with incorrectly diagnosed cardiac arrhythmias by ECG or Holter recording then distinguished to be ECG artifacts were included in this study. The patients were collected from the author’s private practice in the northern Iraqi governorate of Sulaimanya during the period from June 2015 to August 2020. The differentiation of the artifact waves from the arrhythmias were made by careful inspection of the ECG, identification of the R waves within the artifact waves and correlating the artifact waves with the patient’s symptoms. Results: The artifacts were mistaken for ventricular fibrillation in two patients, ventricular tachycardia in four, atrial fibrillation in two, atrial flutter in four, and in one patient bradycardia of high grade atrio-ventricular block. Conclusion: Distinguishing artifact in ECG and differentiating them from cardiac arrhythmia is important to avoid mismanagement.

Wide QRS complex tachycardia (WCT) is a common clinical challenge, and can present in a variety of settings, including the emergency department, in the in-hospital setting, during operations, and even in the outpatient arena. The proper, and timely, acute management of WCT is contingent on the proper evaluation and diagnosis of the tachycardia. WCT, an arrhythmia with a QRS duration of over 120 ms, at a rate of over 100 beats per minute, can be due to either supraventricular tachycardia with aberrant conduction or due to ventricular tachycardia. The management of these two entities can vary considerably, especially if the patient presents without significant haemodynamic stability.

Wolff Parkinson White Syndrome

Syncope is a common manifestation of both hypertrophic cardiomyopathy (HCM) and Wolff-Parkinson-White (WPW) syndrome. The most common arrhythmia in HCM is ventricular tachycardia (VT) and atrial fibrillation (AF). While preexcitation provides the substrate for reentry and supraventricular tachycardia (SVT), AF is more common in patients with preexcitation than the general population. Concurrence of HCM and WPW has been reported in many cases, but whether the prognosis or severity of arrhythmia is different compared to the individual disorders remains unsettled. We report a case of HCM and Wolff-Parkinson-White (WPW) syndrome in a 28-year-old male Nigerian soldier presenting with recurrent syncope and lichen planus.

Sinus Bradycardia

CARDIAC ARRHYTHMIAS CAN BE found in the fetus and the neonate. Arrhythmias that are seen in the neonate include sinus bradycardia and tachycardia, premature atrial and ventricular contractions, supraventricular tachycardia, atrial flutter, ventricular arrhythmias, and heart block. Although infants with structural or functional anomalies can have arrhythmias, many arrhythmias result from noncardiac causes, such as hypoxemia and acidosis.1

Diagnostic Codes

Background: Arrhythmias are relatively common in patients with non-ischemic cardiomyopathies. There are limited data on the association of atrial and ventricular arrhythmias with outcomes in patients with peripartum cardiomyopathy (PPCM). Methods: We queried the 2003-2011 Nationwide Inpatient Sample databases using the ICD-9 diagnostic codes 674.50 to 674.55, to identify all women aged between 15-55 years admitted with a diagnosis of PPCM. The various arrhythmias were identified using appropriate ICD-9 diagnostic codes - atrial fibrillation (AF) (427.31), atrial flutter (427.32), supraventricular tachycardia (SVT) (427.0), ventricular tachycardia (VT) (427.1), ventricular fibrillation (VF) (427.41 and 427.42). Multivariable adjusted logistic regression was used to study the association of arrhythmias with in-hospital mortality and multivariable adjusted linear regression was used to study the association of arrhythmias with length of stay and hospital charges. Results: From 2003 to 2011, 34,944 patients were hospitalized with PPCM. The mean age was 30±7 years. Among these patients with PPCM, ventricular tachycardia (VT) (4.8%) was the most common arrhythmia followed by atrial fibrillation (AF) (2.2%), ventricular fibrillation (VF) (1.3%), atrial flutter (0.8%) and supraventricular tachycardia (SVT) (0.6%). The risk adjusted in-hospital mortality was higher in PPCM patients with AF (3.6% vs 1.2%, adjusted OR 2.38, 95% CI 1.50-3.78), VT (3.7% vs 1.1%, adjusted OR 1.8, 95% CI 1.30-2.48) and VF (14.2% vs 1.1%, adjusted OR 5.39, 95% CI 3.75-7.74) compared to those without arrhythmias. Among the study population, the average length of stay was longer in patients with AF (8 vs 5 days, p<0.001), atrial flutter (10 vs 5 days, p<0.001), SVT (10 vs 5 days, p<0.001), VT (9 vs 5 days, p<0.001) and VF (10 vs 5 days, p<0.001). The average hospital charges was also higher in patients with AF ($74,799 vs $40,974; p=0.004), atrial flutter ($129,692 vs $41,042; p<0.001), SVT ($133,223 vs $41,165; p<0.001), VT ($97,525 vs $38,929; p<0.001) and VF ($158,381 vs $40,194; p<0.001). Conclusions: In patients hospitalized with PPCM AF, VT and VF were independently associated with significantly higher in-hospital mortality. Also in these patients AF, atrial flutter, SVT, VT and VF were independently associated with higher hospital charges and longer length of stay.
