Cardiotoxicity is the occurrence of heart dysfunction as electric or muscle damage, resulting in heart toxicity. [1] This can cause heart failure, arrhythmia, myocarditis, and cardiomyopathy in patients. [2] Some effects are reversible, while in others, permanent damage requiring further treatment may arise.
Heart disease and cardiovascular disease have almost the same meaning. ... Heart tissue scarring from a previous heart attack or other cause. Cardiomyopathy. Electrical heart abnormalities ...
Causes: Coronary artery disease, congenital heart defect, major blood loss, lack of oxygen, electrical injury, very low potassium, heart failure, myocardial infarction: Diagnostic method: Finding no pulse, [1] ECG (EKG) [4] Prevention: Not smoking, physical activity, maintaining a healthy weight, healthy eating [5] Treatment
This results in the heart being less able to pump blood effectively and also may cause electrical conduction problems. [3] Specifically, within the bundle branches that conduct impulses through the interventricular septum and into the Purkinje fibers, as these are responsible for the depolarization of contractile cells of both ventricles. [11]
Arrhythmias are due to problems with the electrical conduction system of the heart. [2] A number of tests can help with diagnosis, including an electrocardiogram (ECG) and Holter monitor. [5] Many arrhythmias can be effectively treated. [2] Treatments may include medications, medical procedures such as inserting a pacemaker, and surgery. [6]
Cardiac causes include acute or chronic ischemic heart disease, vascular heart disease, valvular heart disease, or degenerative primary electrical disease. Ultimately, the causes act by three mechanisms: depressed automaticity of the heart, conduction block, or escape pacemakers and rhythms.
