What is the difference between AFib and cardiomyopathy?
AFib makes the ventricles beat faster to push blood out of the heart. Beating too fast for a long time can make the heart muscle too weak to pump enough blood to your body. This is called cardiomyopathy.
What is an apical hypertrophic cardiomyopathy?
Apical hypertrophic cardiomyopathy (AHCM or ApHCM), also known as Yamaguchi syndrome, is a rare form of hypertrophic cardiomyopathy which usually involves the apex of the left ventricle, rarely involves the right ventricular apex, or involves both apices.
Why does hypertrophic cardiomyopathy cause atrial fibrillation?
Atrial fibrillation is not a “second disease.” HCM tends to lead to atrial fibrillation for many patients. Over a long period of time, the increased pressures in the heart tend to lead to greater size of the left atrium The abnormal cellular structure of the HCM heart may also make HCM patients prone to afib.
Can takotsubo cause atrial fibrillation?
Takotsubo cardiomyopathy may be associated with some critical complications such as heart failure, life-threatening arrhythmias, atrial fibrillation, long QTs, thromboembolic events, the recurrence of TTC, left ventricular outflow obstruction, mitral valve regurgitation, and cardiac rupture.
What is heart shock treatment?
Cardioversion is a medical procedure that restores a normal heart rhythm in people with certain types of abnormal heartbeats (arrhythmias). Cardioversion is usually done by sending electric shocks to your heart through electrodes placed on your chest.
How does hypertrophic cardiomyopathy cause arrhythmia?
However, in a small number of people with HCM , the thickened heart muscle can cause shortness of breath, chest pain or problems in the heart’s electrical system, resulting in life-threatening abnormal heart rhythms (arrhythmias) or sudden death.
Does hypertrophic cardiomyopathy cause atrial fibrillation?
Atrial fibrillation (AF) is the most common sustained arrhythmia in hypertrophic cardiomyopathy (HCM). It is reported by ≈20% of patients evaluated at referral centers and is more frequent in older patients and patients with left ventricular (LV) outflow obstruction.
How serious is apical hypertrophic cardiomyopathy?
Apical hypertrophic cardiomyopathy in North American patients is not associated with sudden cardiac death and has a benign prognosis in terms of cardiovascular mortality. Nevertheless, one third of these patients experience serious cardiovascular complications, such as myocardial infarction and arrhythmias.
What are symptoms of apical hypertrophic cardiomyopathy?
Symptoms
- Chest pain, especially during exercise.
- Fainting, especially during or just after exercise or exertion.
- Heart murmur, which a doctor might detect while listening to your heart.
- Sensation of rapid, fluttering or pounding heartbeats (palpitations)
- Shortness of breath, especially during exercise.
