As a whole, cocaine-associated electrocardiographic abnormalities are well described in the literature (primarily in the form of observational studies, small controlled studies and case reports).

Eleven studies describing sinoatrial (SA) nodal, atrioventricular (AV) nodal or infra-Hisian conduction parameters in the setting of cocaine use were found. Fourteen studies and two case series ...

but occasional P waves do conduct through the AV node to produce a QRS complex. Complete heart block is usually symptomatic from the slow ventricular rates. These symptoms include fatigue ...

Two patients had cardiac side effects after LCM loading, one (3.0%) with new-onset first-degree AV block and the other (3.0%) with atrial premature complex. For the quantitative changes of ECG ...

The remaining physical examination was unremarkable. Figure 1 exhibits his initial ECG. The ECG shows a wide QRS complex tachycardia with irregular RR intervals, delta waves and no P waves, findings ...

You may have heard that eating complex carbs is better than simple carbs. But nutrition labels don’t always tell you if the carbohydrate content is simple or complex. Complex carbohydrates are ...

The presence of type I second-degree AV block with a narrow QRS complex is almost invariably localised in the AV node. One should remember that what appears to be narrow QRS type II block may be a ...

Ltd.) with three metal subcutaneous hook-electrodes. After 5 min of isoflurane anesthesia, stable heart rate (HR), P-R interval, and the wave form of QRS complex were recorded as baselines. Then ...
