Arrhythmias following Revascularization Procedures in the Course of Acute Myocardial Infarction: Are They Indicators of Reperfusion or Ongoing Ischemia?

Table 3

Comparison of the frequency of various reperfusion arrythmias between primary percutaneous coronary intervention and thrombolytic treatment groups of patients.

	Treatment		𝑃
	Primary PCI; (𝑛=54)	Thrombolytic; (𝑛=97)
	Mean ± SD (median)	Mean ± SD (median)
	𝑛 (%)	𝑛 (%)
Reperfusion arrythmias*	45 (83.3%)	86 (88.7%)	0.355
AIVR	27 (50%)	71 (73.2%)	0.004
Sustained VT	4 (7.4%)	5 (5.2%)	0.575
Nonsustained VT	31 (57.5%)	68 (70.1%)	0.116
Ventricular fibrillation**	2 (3.7%)	0 (0%)	0.126
AV Block	3 (5.6%)	6 (6.2%)	0.875
Frequent PVCs	5 (9.3%)	17 (17.5%)	0.168
Atrial fibrillation	7 (13%)	26 (26.8%)	0.049

PCI: percutaneous coronary intervention, 𝑛: number of patients, SD: standard deviation, AIVR: accelerated idioventricular rhythm, VT: ventricular tachycardia, AV: atrioventricular, and PVCs: prematüre ventricular contractions.
*Detected in the first 48 hours.
Chi-square test and **Fisher’s Exact Chi-square tests were performed to analyse data.
