There is nothing called Idiopathic VPDs . . . It may simply reflect our Ignorance !

VPDs are such a common cardiac arrhythmia . We also know most are benign .Still modern science demands to rule out structural heart disease in any patient with multiple VPDs. When ventricles get irritated it reacts with VPDs . ( The irritants  can be anatomical , physiological or primary electrical) Echo can detect only anatomical irritants .We are recognising  more such focus for VPDs . Hence idiopathic VPDs  may simply reflect our ignorance !  A focused  echocardiogram is  required . The following conditions are often observed in patients  with recurrent VPDs Posterior Mitral annular calcification (Especially in women ) -Annular VPDs Aortic valve degeneration /Bicuspid aortic valve with calcification – Cuspal VPDs Mitral valve prolapse in young -Stretch induced  Pap muscle VPDs Minimal  pericardial effusions with adherent epicarditis LV false tendons-Stretch VPDs RVOT lipid focus -Subclinical ARVD LVH and Hypertension -Fibrotic VPDs     Asymmetric septal hypertrophy Scars in MI/ DCMs infiltrations in RCMs (Any Interstitial heart disease ) (Conditions 7 and 8 are  common disorders myocardium  just included to  complete the list ) **Please note ,above mentioned entites are anatomical irritants .There is a whole lot of physiological  irritants that can induce VPDs .  ( Hypoxia, Excess catecholamines ,  K + fluxes ,  acidotic milieu etc ) . *** Another group is primary electrical diseases inherited channel disease can induce VPDs Also read A crash c...
