HCN4 gain-of-function mutation increases intrinsic heart rate and limits maladaptive remodeling under pressure overload

IntroductionGain-of-function (GOF) mutations in the cardiac pacemaker channel HCN4 have been associated with inappropriate sinus tachycardia in human patients. Chronic tachycardia is generally associated with adverse cardiac remodeling and cardiomyopathy, but whether enhanced HCN4 activity can induc...
