What is cardiomyopathy
Heterogeneous group of diseases associated with mechanical and electrical dysfunction resulting in hypertrophy or dilation of ventricles
The hallmarks of cardiomyopathy are

Peripartum
Tachycardia induced
HCM a purely genetic cardiomyopathy occurs as a result of ……
Mutation in B myosin binding protein and myosin binding protein C
The signs of HCM include
Fainting attacks on activity
SAM -systolic Anterior mitral motion
Jerky pulse
The treatment options for HCM are
Surgery
Alcohol infusion or ablation
B blockers main therapy
The main therapy for HCM is
Beta blockers
The prevalence of HCM and ARVC are
1:500
1:5000
The treatment option for ARVC are
B blockers
ICD implantable cardioverter difibrillator
The pathogenesis of ARVC is
Loss of cardiac cells due to appptosis in the right ventricle
