The key difference between dilated cardiomyopathy and hypertrophic cardiomyopathy is that in dilated cardiomyopathy, the left ventricle dilates and restricts the pumping of blood, while in hypertrophic cardiomyopathy, the ventricles and interventricular septum thicken, constrict, and restrict the pumping of blood to the body. Cardiomyopathy is a disease in the heart muscles where it is […]

The key difference between valvular and non-valvular AF is that valvular AF is a type of atrial fibrillation caused due to a problem with a heart valve, while non-valvular AF is a type of atrial fibrillation that is not caused due to a problem with a heart valve. Atrial fibrillation (AF) is a state of […]

The key difference between fibrillation and fasciculation is that fibrillation is the abnormal rhythm of atria that takes place in cardiac muscles, while fasciculation is the contraction and relaxation of skeletal muscles. Each muscle tissue in the body possesses a unique structure and function. Cardiac muscles facilitate contractions in the heart to pump blood, while […]

The key difference between massive and submassive pulmonary embolism is that massive pulmonary embolism is the obstruction of the pulmonary artery with systemic hypotension, while submassive pulmonary embolism is the condition where individuals suffer from pulmonary embolism with right ventricular dysfunction or myocardial necrosis but without systemic hypotension. Pulmonary embolism is a disease condition caused […]

The key difference between atrial and ventricular septal defect is that atrial septal defect is a condition characterized by a hole in the wall between the heart’s two upper chambers, while ventricular septal defect is a condition characterized by a hole in the wall between the heart’s two lower chambers. Congenital heart defects are a […]

The key difference between atrial fibrillation and ectopic beats is that atrial fibrillation is a condition of the heart characterized by an irregular rhythm with an abnormally fast heartbeat, while ectopic beats or ectopic heartbeats are extra or missed heartbeats before a regular beat. Atrial fibrillation and ectopic beats are two conditions of the heart […]

The key difference between polymorphic and monomorphic ventricular tachycardia is that polymorphic ventricular tachycardia is a type of abnormally fast heart rate with a continuously varying QRS complex morphology in a surface electrocardiogram, while monomorphic ventricular tachycardia is a type of abnormally fast heart rate with uniform QRS complexes within each lead in a surface electrocardiogram. Ventricular tachycardia […]

The key difference between PFO and ASD is that the PFO is a heart defect that occurs due to the failure of closing the foramen ovale after birth, while the ASD is a heart defect in which blood flows between the right atria and left atria of the heart due to a failure of forming […]

The key difference between triple bypass and open heart surgery is that an open heart surgery is a surgical procedure involving the complete opening of the chest cavity while triple bypass surgery is a procedure of open heart surgery. It is performed when three coronary vessels have to be grafted in order to overcome three […]
