Drugs for Heart Conditions

pump outgrows blood supply and stiffens

Myocardial hypertrophy is a dangerous condition because

pump outgrows blood supply and stiffens

increased contractility is not useable

increased metabolic demand

heart outgrows available space

As a Dysrhythmic drug, Beta Blockers

effect Ca2+

effect Na+

effect K+

effect K+/Cl- pump
