All are the true regarding hyperophic obstructive cardiomyopathy, except:
Answer is A (Digitalis is useful) Repeat Digitalis is contraindicated in hyperophic obstructive cardiomyopathy (HOCM). Digitalis causes an increase in myocardial contractility which increases the degree of obstruction in HOCM and worsens the condition. Drugs Contraindicated in HOCM are Drugs that increase myocardial Contractility DigitalisQ Sympathomimetic aminesQ b agonist Drugs which decrease ventricular volume (preload) NitratesQ DiureticsQ Any increase in myocardial contractility or decrease in ventricular volume (preload) increase the degree of obstruction in HOCMQ
Digitalis is useful
Left ventricular outflow obstruction
Asymmetrical septal thickness
Double apical impulse
