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

Table 5

Association between the occurrence of reperfusion arrythmias and ST segment regression in primary PCI and thrombolytic treatment groups.

Treatment	ST segment regression	Reperfusion arrythmias (in the first 48 hours)		𝑃
		Present	Absent
		𝑛 (%)	𝑛 (%)
Primary PCI	<50%	10 (22.2%)	1 (11.1%)	0.450
	>50%	35 (77.8%)	8 (88.9%)
Thrombolytic	<50%	40 (46.5%)	10 (90.9%)	0.006 *
	>50%	46 (53.5%)	1 (9.1%)

PCI: percutaneous coronary intervention, 𝑛: number of patients.
Chi-square test was performed to analyse data. *Values of 𝑃<0.05 indicate statistically significant data.
