Atrial fibrillation (AF) is the most common arrhythmia noted in clinical practice and its incidence and prevalence are on the rise. The single most important intervention is the evaluation and treatment of stroke risk. Once the risk for stroke has been minimized, controlling the ventricular rate and treating symptoms become relevant. In this review article, we emphasize the importance of confirming and treating the appropriate arrhythmia and correlating symptoms with rhythm changes. Furthermore, we evaluate some of the risk factors for AF that independently result in symptoms, underlining the need to treat these risk factors as part of symptom control. We then discuss existing and novel approaches to rate control in AF and briefly cover rhythm control methods.

BackgroundCommunity management of atrial fibrillation (AF) often requires the use of electrocardiographic (ECG) investigation. Patients discharged following treatment of AF with fast ventricular response (fast AF) can require numerous ECGs to monitor rate and/or rhythm control. Single-lead ECGs have been proposed as a more convenient and relatively accurate alternative to 12-lead ECGs for rate/rhythm management and also diagnosis of AF. We aimed to examine the feasibility of using the AliveCor single-lead ECG monitor for diagnosis and monitoring of AF in the community setting.MethodsDuring the course of 6 months, this evaluation of a clinical service improvement pathway used the AliveCor in management of patients requiring (1) follow-up ECGs for AF with previously documented rapid ventricular rate or (2) ECG confirmation of rhythm where AF was suspected. Twelve AliveCor devices provided to the acute community medical team were used to produce 30 s ECG rhythm strips (iECG) that were electronically sent to an overreading physician.ResultsSeventy-four patients (mean age 82 years) were managed on this pathway. (1) The AliveCor was successfully used to monitor the follow-up of 37 patients with fast AF, acquiring a combined total of 113 iECGs (median 1.5 ±3.75 per patient). None of these patients required a subsequent 12-lead ECG and this approach saved an estimate of up to £134.49 per patient. (2) Of 53 patients with abnormal pulses, the system helped identify 8 cases of new onset AF and 19 cases of previously known AF that had reverted from sinus back into AF.ConclusionsWe have demonstrated that the AliveCor system is a feasible, cost-effective, time-efficient and potentially safer alternative to serial 12-lead ECGs for community monitoring and diagnosis of AF.

Aspergillus can cause devastating opportunistic infections in immunocompromised patients. Rarely does this fungus invade the heart, and when it does, survival is especially poor despite optimal medical and surgical treatment. We report a case of cardiac aspergilloma with involvement of the tricuspid valve and both the right atrium and ventricle found on a transthoracic echocardiogram in an immunocompromised patient after developing atrial fibrillation with rapid ventricular rate. The findings from this case suggest that early clinical suspicion is critical in early diagnosis and thus early treatment.

Digoxin is used for heart failure associated to systolic dysfunction and high ventricular rate. It has a narrow therapeutic range and intoxication may occur due to drug interactions or comorbidities. The aim of this work was to study digoxin use in a public health unit delineating the profile of patients susceptible to digitalis intoxication. Medical records belonging to patients admitted to the cardiomyopathy ward of the health unit (2009-2010) and in use of digoxin were analyzed. Among 647 patients admitted, 185 individuals using digoxin and possessed records available. The registration of plasma digoxin concentration was found in 80 records and it was out of the therapeutic range in 42 patients (52.5%). This group of individuals was constituted mainly by males patients (79%), functional class III of heart failure (65%), exhibiting renal failure (33%). The evaluated sample reflects the epidemiology of heart failure in Brazil and, although pharmacotherapy had been according to Brazilian Guidelines, apparently the monitoring was not performed as recommended. This work highlighs the necessity of plasma digoxin constant monitoring during pharmacotherapy and the development of protocols that enable a safer use, especially in male patients, functional class III and with renal dysfunction.
