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
By Dr. Mustafa Toma and Dr. Christopher Cheung on May 27, 2015
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.

In patients presenting with acute decompensated heart failure and previously on oral loop diuretics at home, there is no difference between low-dose and high-dose furosemide, or bolus and continuous infusions, on the patient’s global assessment of symptoms and changes in serum creatinine at 72 hours.

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.

Spironolactone or eplerenone should be added to BB and ACEi/ARB in NYHA class II HF patients with EF < 30-35% in the absence of significant renal impairment or hyperkalemia.

I now strongly consider using dabigatran instead of warfarin in patients with a CHADS score of 2 or higher.

I generally started with thiazide diuretics (due to cost and proven effectiveness) then added either an ACE inhibitor (ACEi) or a calcium channel blocker (CCB), consistent with the Canadian Hypertension Society Guidelines.

Since their introduction, certain contraindications and side effects have been well known, including worsening heart failure, edema (including macular edema) and weight gain.
