Here is a rhythm strip from a 3-lead Holter ECG. It comes from a 56-year-old man with arterial hypertension and no other previous cardiac diseases. Recently, the patient has noticed that pulse irregularities occur during blood pressure measurement (which he performs himself at home).
On the ECG, first a sinus beat, then a PVC, then an AIVR occurs, which is interrupted by another PVC, then sinus rhythm again.
The heart rate of the AIVR fluctuates slightly and is around 55 pbm. A significantly lower heart rate would be expected with a ventricular escape rhythm. AIVR is seen more frequently as a reperfusion arrhythmia in patients with coronary artery disease. It also rarely occurs independently of coronary heart disease. It does not generally require treatment.
