During S1, the (a)   of first sound is slightly precedes the​ (b)  

• Mitral Component
• Tricuspid Component
• Aortic Component
• Pulmonic Component

During S2, the (a)   of first sound is slightly precedes the​ (b)  

• Pulmonic Component
• Aortic Component
• Mitral Component
• Tricuspid Component

Different type of Electrocardiography (EKG)

• 12-lead ECG

• Continuous monitoring

• Discontinuous monitoring

• 13-lead ECG

Examples of Electrocardiography (ECG) Continuous monitoring

• Hardwire

QRS complex

percentage of end-diastolic volume ejected with each heartbeat from the left ventricle

• Pulse pressure
• Cardiac output
• Stroke volume
• Ejection fraction
• Cardiac input

amount of blood pumped by the left ventricle in liters per minute

• Cardiac output

• Ejection fraction

• Echocardiography

• Pulse Pressure

• After load

How to get Cardiac output

• Cardiac Output = Heart Rate x Stroke Volume
• Cardiac Output = Heart Rate / Stroke Volume
• Cardiac Output = Heart Rate + Stroke Volume
• Cardiac Output = Respiratory Rate x Stroke Volume
• Cardiac Output = Blood Pressure x Heart Rate

Range of a normal cardiac output

• 5 to 9 liters per minute
• 4 to 6 liters per minute

• 2 to 6 liters per minute
• 3 to 7 liters per minute
• 6 to 10 liters per minute
