Electrical Events
What is the QRS complex?
Part of an ECG represents ventricular depolarization
What is the pulmonary valve?
Blood passes through when this valve when it exits the right ventricle into the pulmonary artery
What is the P wave?
This ECG wave represents atrial depolarization
What is systole?
Phase which occurs the heart muscle contracts & pumps blood.
What is a heart murmur?
Abnormal sound is caused by turbulent blood flow, often due to valve problems
What is the aortic valve?
This valve prevents back-flow of blood into the left ventricle
What is the T wave?
This ECG wave shows the ventricles
What is diastole?
Phase which heart muscle relaxes and allows chambers to fill with blood.
The “dub“ sound heard in the heart is created by the closing of these valves.
What is the right atrium?
The order of blood flow through the heart starts here.
what are the bundle branches?
Conduction pathway carries impulses through the inter-ventricular septum.
What are the atrioventricular (AV) valves?
The heart sound “lub” is caused by the closing of these valves.
What is the mitral (bicuspid) valve?
This valve opens to allow blood flow from the left atrium to left ventricle.
