The Ideal

BACKGROUND: Temporary pacing leads with electrodes are a potential risk, because microshock inadvertently transmitted across the catheter or wire can paradoxically cause lethal dysrhythmias. Much attention has been paid to this complication in clinical guidelines, but little is known about actual practices used to protect patients. OBJECTIVES: A national survey was done to describe current practices related to the care of patients with temporary epicardial or transvenous pacing catheters. The survey focused on environmental factors that affect generation of static electricity, equipment used with temporary pacing, and nursing practices used when handling temporary pacing electrodes. METHODS: The Pacemaker Electrical Care and Safety Survey was developed, validated, and pilot tested before it was mailed to all 895 hospitals that perform cardiac surgery. Surveys were sent to the coronary care unit, cardiac surgical ICU, and telemetry units of each hospital. RESULTS: Responses were received from 476 units representing 388 (43%) of the 895 institutions. Most respondents reported using gloves, although few hospitals had policies mandating this practice. The insulating materials used most often, in order, were a glove or finger cot, tape, and gauze. Few units (25%) use any measure to reduce static electricity generated by movement over carpeting. Little attention was paid to insulating exposed epicardial temporary pacing electrodes at the generator. CONCLUSIONS: Temporary pacing electrodes were usually handled in an electrically safe manner; however, little attention was paid to environmental sources of microshock or connections between the generator and the cable. Although the respondents reported using a variety of insulating materials, the ideal cover for the exposed tips of the electrodes has not yet been determined.

The Creation

SummaryAnalysis of electrocardiograms tape-recorded from patients admitted to hospital with acute myocardial infarction revealed that the pattern of ventricular extrasystolic activity was not significantly different among those who subsequently developed ventricular fibrillation and those who did not. Episodes of ventricular fibrillation occurred predominantly within 4 hours from the start of infarction. Patients were 3 times less likely to survive an episode of ventricular fibrillation if they also had left ventricular failure than if this feature was absent. Management of episodes of ventricular fibrillation was compared in patients before and after the creation of a specially staffed and equipped coronary care unit. The success of electric shock as a treatment for ventricular fibrillation was similar before and after the creation of the coronary care unit. An attempt was made to determine which features in the management of ventricular fibrillation in this and in previously published series were associated with patient survival.

SummaryAntithrombin III (At-III) was measured at the time of admission and two days later in 131 patients laid up in a coronary care unit. The patients were examined for deep-vein thrombosis (DVT) clinically and by means of 125I-fibrinogen scanning. 19 patients developed DVT. In 11 subjects with and 25 without DVT At-III decreased more than 10%. And in 7 with and 17 without DVT At-III decreased more than 15%. One person with DVT had subnormal At-III. By using decrease of At-III or subnormal initial At-III to predict DVT the following predictive value (PV) were found. Decrease ≤ 10%, PV pos.= 0.32 and PV neg. = 0.93. Decrease ≤ 15%, PV pos. = 0.32 and PV neg. = 0.90. The positive predictive values obtained were too low to let decreasing At-III give occasion for prophylactic anticoagulant treatment.

Skewness And Kurtosis

Despite the unmistakable beneficial effect of clopidogrel on platelet aggregation,still there are some patient poorly responds to clopidogrel that may lead to worse cardiovascular clinical events.One hundred and twenty seven patients with cardiovascular disease (ACS,stroke,or TIA) were enrolled as a study group. Patients were recruited at coronary care unit (CCU) of Al-Yarmouk Teaching Hospital. Paletlet assessment was done by using light transmission aggregometry. between the patients that enrolled in this study there are significant inter-individual variability both skewness and Kurtosis were negative (-0.450,-0.130) respectively. 24% of patient enrolled in this study were hyporesponder.
