Step by step cardiac cycle
網頁The cardiac cycle is a series of contractions that ensure blood is flowing in the correct direction The cycle is broken down into three stages: • Cardiac Diastole – the entire heart is relaxed • Atrial Systole, also known as Ventricular Diastole • Ventricular Systole, also known as Atrial Diastole Cardiac Diastole 網頁Below is a summary of the key steps involved in the cardiac conduction cycle. Clinical significance: Artificial pacemakers An artificial pacemaker is a medical device that is able to monitor and regulate heart rate and rhythm.
