Cardiac Output = stroke volume X heart rate
Chronotropy changes in heart rate
Stroke Volume Depends On... preload contractility or ionotropy afterload
Preload Determined By... venous return residual volume
Ionotropy intrinsic ability of cardiac muscle fiber to contract at given fiber length
Afterload Increased By... increased total peripheral resistance or blood pressure increased ventricular volume decreased ventricular wall thickness
Blood Pressure = cardiac output X total peripheral resistance

Distensibility or Lusotropy ease of ventricular filling in diastole (ability to stretch)
