Cardiac - Rhythm

Your heart rhythm naturally fluctuates based on activity, stress, or sleep. However, it is considered abnormal (an arrhythmia) when it is inappropriately fast, slow, or irregular. : A fast resting heart rate exceeding 100 bpm. Bradycardia : A slow resting heart rate below 60 bpm.

Cardiac rhythm is the regular pattern of your heartbeat, controlled by the heart’s internal electrical system. In a healthy adult at rest, this rhythm typically falls between 60 and 100 beats per minute (bpm). Normal Cardiac Rhythm cardiac rhythm

: Ventricular contraction (bottom chambers pumping blood to the lungs and body). T Wave : Ventricular recovery (preparing for the next beat). Common Variations and Abnormalities (Arrhythmias) Your heart rhythm naturally fluctuates based on activity,

: Atrial contraction (top chambers pumping blood to the bottom chambers). Bradycardia : A slow resting heart rate below 60 bpm

: An irregular and often rapid heart rhythm that can increase the risk of stroke or heart failure.

: A common, harmless variation where the heart rate slightly increases during inhalation and decreases during exhalation.
