EKG – difference between MAT and PAT

MAT stands for multifocal atrial tachycardia. PAT stands for Paroxysmal atrial tachycardia. A student going through drbeen’s EKG interpretation lectuers asked us the difference between MAT (multifocal atrial tachycardia) and PAT (paroxysmal atrial tachycardia). Here is a quick summary of the differences:  PAT is usually an extra focus/reentrant circuit in the atria. It is similar … Continue reading EKG – difference between MAT and PAT

Pulmonary Circuit

Properties of Pulmonary Circuit The heart pumps a volume of blood into the lungs which after getting oxygenated is transported back to heart. This oxygenated blood is then pumped out of the heart and into the aorta and subsequently into the systemic circulation. As a consequence, at any given time the lungs (pulmonary vasculature) contain … Continue reading Pulmonary Circuit

General Principles of Hemodynamics

Organization of Cardiovascular System The human heart has 4 chambers which are the two atria and the two ventricles. These 4 chambers are divided into 2 functional units referred to as the left heart and the right heart. These atria and ventricle are single functional unit, separated by the atrioventricular valves. These AV valves are … Continue reading General Principles of Hemodynamics
