BACKGROUND Electrophysiological study (EPS) after myocardial infarction may have a role in identifying patients at risk of sudden cardiac death. It has been shown previously that inducible very fast ventricular tachycardia (VT; cycle length [CL], 200-230 ms) is predictive of arrhythmia recurrence; however, its significance early after reperfusion in ST-segment-elevation myocardial infarction is...

The present study aimed to investigate the in-hospital and long-term prognostic value of fragmented QRS complex (fQRS) for microvascular reperfusion and changes in left ventricular (LV) function in patients with ST elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI). A total of 216 patients with STEMI undergoing primary PCI were included in the...

Activation of the parasympathetic nervous system has been reported to have an antiarrhythmic role during ischemia–reperfusion injury by decreasing arrhythmia triggers. Furthermore, it was that neurotransmitter acetylcholine is able modulate ATP-dependent potassium current (I K-ATP ), a crucial activated hypoxia. However, possible significance this modulation in mechanism not fully clarified. Ac...

AIMS We sought to generate a mouse Langendorff model of ischaemia-induced ventricular fibrillation (VF) that does not depend on triggers such as programmed electrical stimulation. METHODS AND RESULTS Hearts from male Tuck Ordinary mice were perfused with Krebs solution (modified to contain low-normal K(+), 3 mmol/L, and high Ca(2+), 2.4 mmol/L) containing different combinations of catecholami...
