This article focuses on the case reports of phase 4 paroxysmal atrioventricular block. Rate-dependent conduction disturbances may be responsible for atrioventricular (AV) block and called paroxysmal AV block. The purpose of this article is to illustrate some cases concerned with this specific form of AV block, which developed spontaneously rather through provocation during the slowing of the heart rate. Case 1, a 24-year-old male patient with a history of myocarditis, was followed for 3 years with stabilized ECG abnormalities. He was at that time physically fit. However, at times, intensity of heart sounds varied with an apparent arrhythmia. Case 2 was a 66-year-old male patient suffering from coronary artery disease but with neither angina nor infarction.

    Background Previous studies indicate that decreased heart-rate variability (HRV) is related to the risk of death in patients after acute myocardial infarction (AMI). However, the conventional indices of HRV have poor predictive value for mortality. Our aim was to develop novel predictive models...

    Background: Acute myocarditis may mimic myocardial infarction, since affected patients complain of "typical" chest pain, the ECG changes are identical to those observed in acute coronary syndromes, and serum markers are increased. We describe a case series of presumptive myocarditis with ST...
