[Symptoms and electrocardiographic findings in cardiomyopathies].
Based on the national surveys in Japan, the most common symptoms of dilated cardiomyopathy(DCM) were dyspnea, palpitation, general fatigue and edema. Palpitation, dyspnea, general fatigue and anginal pain were common in hypertrophic obstructive cardiomyopathy(HOCM) and hypertrophic non-obstructive cardiomyopathy (HNOCM). Dyspnea was the most common symptom in constrictive cardiomyopathy (RCM). Electrocardiographic findings in DCM were not specific, and ST-T change, wide QRS complex, left ventricular hypertrophy and abnormal Q wave were frequently observed. In both of HOCM and HNOCM, frequent electrocardiographic abnormalities were ST-T abnormality, left ventricular hypertrophy and wide QRS complex. Moreover, abnormal Q wave was frequently observed in HOCM. Ventricular arrhythmia, including fatal ventricular tachycardia or ventricular fibrillation, was frequently found in patients with any type of cardiomyopathy.
