Diastole (section Role in cardiac cycle) Diastole (/daɪˈæstəli/ dy-AST-ə-lee) is the relaxed phase of the cardiac cycle when the chambers of the heart are refilling with blood. The contrasting... |
Systole (/ˈsɪstəli/ SIST-ə-lee) is the part of the cardiac cycle during which some chambers of the heart contract after refilling with blood. The term... |

corresponding volume change (isometrically). This short-lasting portion of the cardiac cycle takes place while all heart valves are closed. The inverse operation... |
Electrocardiography (redirect from Cardiac axis) EKG), a recording of the heart's electrical activity through repeated cardiac cycles. It is an electrogram of the heart which is a graph of voltage versus... |
medicine, a pulse represents the tactile arterial palpation of the cardiac cycle (heartbeat) by trained fingertips. The pulse may be palpated in any... |
The cardiac conduction system (CCS, also called the electrical conduction system of the heart) transmits the signals generated by the sinoatrial node... |
Echocardiography (redirect from Cardiac ultrasound) Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging, using standard ultrasound... |
Defibrillation (redirect from Cardiac defibrillator) synchrony to the cardiac cycle. Although the person may still be critically ill, cardioversion normally aims to end poorly perfusing cardiac arrhythmias,... |
Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, with the other two being skeletal muscle and... |
average calculated blood pressure in an individual during a single cardiac cycle. Although methods of estimating MAP vary, a common calculation is to... |
Cardioversion (category Cardiac procedures) therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle, restoring the activity of the electrical conduction system of the heart... |

Bradycardia (redirect from Cardiac arrhythmia/bradycardia) abnormalities characterized by variations in the cardiac cycle length over 120 milliseconds (longest cycle - shortest cycle). These are the most common type of arrhythmia... |
Muscle contraction (redirect from Cross-bridge cycle) heart relaxes, allowing the ventricles to fill with blood and begin the cardiac cycle again. In annelids such as earthworms and leeches, circular and longitudinal... |
