Note the premature ventricular contraction (PVC) that triggers the AVNRT in this ECG. If a premature atrial contraction (PAC) or premature ventricular contraction (PVC) occurs at the right time, the ...

This is a narrow-complex QRS rhythm which is quite fast. Looking closely at the last part of the QRS complex in leads V1 and V2, P waves can be seen. This is considered a "short RP tachycardia" and is ...

An EKG measures the heart’s electrical activity and can detect various issues, including heart attacks, rhythm abnormalities, and electrolyte imbalances. Seek immediate medical help if you experience ...

The correct diagnosis is atrial fibrillation with PVC and Ashman phenomenon (Figure 2). The rhythm is irregularly irregular without any organized atrial activity. Most of the QRS complexes are narrow, ...

An electrocardiogram, also called an ECG or EKG, is a simple and painless test that measures the electrical impulses of your heart to check for signs of heart disease. It's done through small ...

Attempts to chronically suppress PVCs using antiarrhythmic medications in patients with acute myocardial infarction were associated with higher rate of arrhythmic deaths in the CAST Trial. [72] If ...
