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.
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 ...
