There is regular rhythm at a rate of 42 beats/min. The first five QRS complexes are wide (0.14 sec), and no P waves are seen before or after these QRS complexes; however there appears to be a P wave ...

This case highlights the diagnostic value of Holter ECG monitoring in uncovering spontaneous arrhythmia mechanisms. Several ...

The rhythm is irregularly irregular, with an average rate of 90 beats/min. There is no evidence of any organized atrial activity. Hence, the underlying rhythm is atrial fibrillation. There are two QRS ...

The QRS complex is positive in lead I and negative in lead II and also negative in lead aVF – indicating left axis deviation TIP When you see RBBB always look for 1 st degree heart block and/or left ...

Choice of Psoriasis Treatment Affects CVD Event Rates Increased QRS duration on electrocardiogram (ECG) is an independent predictor of cardiovascular mortality. (HealthDay News) – Increased QRS ...

Low voltage on the ECG is defined as a peak-to-peak QRS amplitude of less than 5 millimeters in the limb leads and/or less than 10 millimeters in the precordial leads. Note: If the gain indicated at ...

QRS Width on ECG Linked to Sudden Cardiac Arrest in CAD For patients with coronary artery disease (CAD), QRS width on electrocardiogram and echocardiographic evidence of heart failure are associated ...

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 ...
