Paired narrow QRS complexes, each preceded by a P wave, certainly raise the possibility of atrial bigeminy. But there are other causes of paired QRS complexes during sinus rhythm. One should look ...
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 ...
There are P waves (+) with regular PP intervals and a rate of 85 beats/min. The P waves have a normal morphology; they are positive in leads I, II, aVF, and V4-V6. This is a stable normal sinus rhythm ...
A specialist tells how to interpret subtle changes on the ECG, including those caused by two life-threatening syndromes you might otherwise miss. Reading ECGs is like learning to appreciate art—it is ...
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 ...

ECG test: What it is and what its results mean
An electrocardiogram (ECG) is a quick test that demonstrates how your heart's electrical activity operates. It is run in both routine health check-ups and emergency situations to detect a range of ...
QRS interval widening appears to be highly specific for the diagnosis of hyperkalemia in patients with end-stage kidney disease. ECG changes, in general, have poor sensitivities for hyperkalemia in ...
