Chronotropic Incompetence refers to the inability of the heart to increase its rate appropriately in response to increased activity or demand, often leading to reduced exercise capacity and symptoms of fatigue. It is a significant marker of cardiovascular dysfunction, particularly in patients with heart failure or after myocardial infarction, and can be assessed through exercise stress testing.

Chronotropic Incompetence

Heart rate is the number of times a person's heart beats per minute, reflecting the heart's ability to meet the body's demands for oxygen and nutrients. It is a crucial indicator of cardiovascular health and can be influenced by factors such as activity level, emotional state, and overall fitness.

Increased activity

Reduced exercise capacity

Symptoms Of Fatigue

Cardiovascular dysfunction refers to the impaired function of the heart and blood vessels, which can lead to inadequate blood flow and oxygen delivery to tissues, potentially causing organ damage. It encompasses a range of conditions including heart failure, arrhythmias, and vascular diseases, often resulting from underlying factors such as hypertension, atherosclerosis, or diabetes.

Cardiovascular Dysfunction

Patients with heart failure

Myocardial infarction, commonly known as a heart attack, occurs when blood flow to a part of the heart is blocked, causing damage to the heart muscle. Prompt medical attention is crucial to restore blood flow and minimize heart damage, often involving medications and surgical interventions.

Myocardial Infarction

Exercise Stress Testing is a diagnostic tool used to evaluate the heart's ability to respond to external stress in a controlled clinical environment. It helps in diagnosing coronary artery disease, assessing the effectiveness of cardiac treatments, and determining safe levels of exercise for patients.
