The aim of this study was to investigate the effect of obesity on dispersion of P-wave duration and QTc interval in obese women. Forty-two obese women (Body mass index (BMI)=40±3 kg/m 2, mean age 45±9 ...

The diagnosis is sinus tachycardia, right ventricular pacemaker, P-wave synchronous ventricular pacing (A-sensed V-paced), pseudo second-degree AV block due to failure of atrial sensing. There is a ...

During the pause, there is a P wave (see arrows in Figure 2), ruling out SA block or sinus arrest right away. The P wave does not occur at the regular PP interval, but it definitely occurs prematurely ...

This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they ...

A new study has linked prolonged P-wave duration to increased risk for sudden cardiac death (SCD), independent of cardiovascular risk factors and atrial fibrillation. 1 This suggests P-wave duration ...

The ECG findings of hyperkalemia change as the potassium level increases. From earliest to latest, the ECG findings include: Peaked T waves best seen in the precordial leads, shortened QT interval and ...

A first-degree atrioventricular node block occurs when conduction through the AV node is slowed, thereby delaying the time it takes for the action potential to travel from the sinoatrial node through ...
