Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality globally. Effective management ...
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 ...
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 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 ...
Background Interpretation of the athlete’s ECG is based on differentiation between benign ECG changes and potentially pathological abnormalities. The aim of the study was to compare the 2010 European ...
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 ...
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 ...
