Sudden death is a well known complication of aortic valve regurgitation and remains a common cause of late mortality after aortic valve replacement. Although malignant arrhythmias have been suggested as the cause of these outcome, there has been little information concerning the frequency and severity of ventricular arrhythmias in patients with aortic valve regurgitation. In order to evaluate the relation between the severity and/or frequency of ventricular arrhythmias and late postoperative results in patients with pure aortic valve regurgitation, 24-hour ambulatory electrocardiographic recordings were obtained before surgery in 107 patients without coronary artery disease. Grading of ventricular arrhythmias was based on a Lown method and compared with hemodynamic data. Ventricular premature beats were observed in 101 patients (94.4%) before operation. Multiformity was found in 10 patients (9.3%) couplets in 19 patients (17.8%) and ventricular tachycardia in 32 patients (29.9%). Patients with severe ventricular arrhythmias (Lown grade 3 or 4: 57.0%) had a higher left ventricular end systolic volume index (LVESVI) 153.1 +/- 76.4 ml/m2 vs 96.5 +/- 35.0 ml/m2 (p = 0.0001); a higher left ventricular end diastolic volume index (LVEDVI) 257.0 +/- 85.4 ml/m2 vs 206.5 +/- 58.3 ml/m2 (p = 0.0009); a lower left ventricular ejection fraction (LVEF) 43.4 +/- 12.5% vs 54.2 +/- 9.8% (p = 0.0001). LVESVI was not related to the severity of ventricular arrhythmias, but was significantly related to the frequency (p < 0.05). All patients with late death were belonging to Lown grade 3 or 4 in severity and more than 30 beats per hour in frequency (28.6%). This study indicates that ventricular arrhythmias are common in patients with aortic valve regurgitation.(ABSTRACT TRUNCATED AT 250 WORDS)

D001145 Arrhythmias, Cardiac Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.

D015716 Electrocardiography, Ambulatory Method in which prolonged electrocardiographic recordings are made on a portable tape recorder (Holter-type system) or solid-state device ("real-time" system), while the patient undergoes normal daily activities. It is useful in the diagnosis and management of intermittent cardiac arrhythmias and transient myocardial ischemia.

D015996 Survival Rate The proportion of survivors in a group, e.g., of patients, studied and followed over a period, or the proportion of persons in a specified group alive at the beginning of a time interval who survive to the end of the interval. It is often studied using life table methods.

D016277 Ventricular Function, Left The hemodynamic and electrophysiological action of the left HEART VENTRICLE. Its measurement is an important aspect of the clinical evaluation of patients with heart disease to determine the effects of the disease on cardiac performance.

D016757 Death, Sudden, Cardiac Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death.
