Supraventricular tachycardia (SVT) is a dysrhythmia characterized by abrupt onset, regular rate that usually exceeds 150 beats/minute, and lack of identifiable P waves on ECG. SVT is caused by an abnormal circuit that allows a wave of depolarization to repeatedly travel in circular fashion in cardiac tissue via a reentry circuit that may reside in the atrioventricular (AV) node or outside the AV node in an accessory pathway.
Mineralocorticoid Receptor Antagonists in Heart Failure with Preserved Ejection Fraction: The TOPCAT and ALDO-DHF trials

There are approximately 500,000 Canadians living with heart failure, and more than 10% in patients older than 65. Up to 50% of patients presenting with signs and symptoms of heart failure will have a preserved ejection fraction (HFpEF or diastolic dysfunction). However, there is a lack of evidence for effective therapies in the management of HFpEF.

Women with myocardial infarction (MI) have a two fold higher rate of no obstructive coronary artery disease (CAD), defined as <50% stenosis in any epicardial coronary artery on angiogram, than men. Despite this, outcomes including death during hospitalization following an MI are higher among women (particularly women <55 years) as compared to men.
