The sound of a heartbeat comes from…
Turbulence of blood flow caused by closure of the valves
Listening to sounds in the body is called
Auscultation
The first heart sound is what valves closing
AV
The second heart sound is caused by what valves closing
Semilunar
Where do you Auscultate the aortic valve
2nd intercostal space to the right of the sternum
Where do you auscultate the pulmonic valve
The second intercostal space to the left of the sternum
Where do you auscultate the Tricuspid and right heart sounds
The fourth intercostal space to the left of the sternum
Where do you auscultate the Mitral and left heart sounds
The fifth intercostal space in the midlclavavicuar line
Electrical events in order for the heart
SA node → junctional fibers→AV node→AV bundle→ bundle branches→ Purkinje fibers
What happens during the P-R interval
Beginning of atrial excitation to beginning of ventricular excitation
What happens during the S-T segment
Entire ventricular myocardium depolarized
What happens during the Q-T interval
Beginning of the ventricular depolarization through ventricular repolarization
What happens during the P wave
Depolarization of the SA node and atria
What happens during the QRS complex
Ventricular depolarization and atrial repolarization
What happens during the T wave
Ventricular repolarization
