A narrow QRS tachycardia at a rate of 105 beats/min. is present. No P waves are identified in front of the QRS complexes, suggesting accelerated AV junctional rhythm. However, there are two PVCs.

Premature ventricular contractions (PVCs) are extra heartbeats that start in the lower part of the heart. Up to 75% of people experience PVCs without symptoms, and they’re usually no cause for concern ...

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 ...

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 ...

The ECG shows sinus rhythm with a rate of about 70 beats per minute and compensatory pauses following late-diastolic premature ventricular contractions. There are prominent ST-T wave abnormalities ...

Sometimes, an abnormal EKG reading is a normal variation in a person’s heart rhythm. In other cases, it may be due to an underlying heart condition or a reaction to medication. An electrocardiogram ...
