Long-Term Follow-up of Patients With Isolated Left Ventricular Noncompaction - Role of Electrocardiography in Predicting Poor Outcome -

Differences in Negative T Waves Between Takotsubo Cardiomyopathy and Reperfused Anterior Acute Myocardial Infarction

“…The 12-lead ECG is the simplest, most widely available, initial clinical diagnostic test. 15 Previous studies, including ours, assessing electrocardiographic differences between these 2 diseases have focused mainly on the acute phase when ST-segment elevation is observed, 6-8 because differential diagnosis is essential for deciding whether reperfusion therapy is required. However, previous studies have reported that negative T waves have already occurred on the ECG at the time of presentation in an appreciable number of patients with TC.…”

Left Ventricular Noncompaction

“…3 Other electrocardiographic (ECG) abnormalities are varied and nonspecific for LVNC. 21 They include left ventricular hypertrophy, repolarization changes, nonspecific S-T segment changes, T-wave inversion, axis shifts, fascicular and bundle branch blocks, and low voltage. 19,22 The absence of repolarization changes on ECG in the inferior leads is associated with a 5-year freedom from cardiovascular death or transplant, but the presence of repolarization changes is nonspecific and of limited usefulness.…”

“…19,22 The absence of repolarization changes on ECG in the inferior leads is associated with a 5-year freedom from cardiovascular death or transplant, but the presence of repolarization changes is nonspecific and of limited usefulness. 21 Left bundle branch block is present in a high percentage of adults with LVNC. Oechslin et al 7 found the incidence of left bundle branch block to be 44% in their study of 34 adults followed for LVNC.…”

The Clinical and Echocardiographic Analysis of Noncompaction Cardiomyopathy in Misdiagnosis and Missed Diagnosis

“…It is also associated with other cardiac and systemic anomalies [6]. Heart failure, thromboembolism and malignant ventricular arrhythmias are the most challenging clinical aspects of NCC [7][8], which contribute to the poor survival in these patients [9]. During the last decade, more attention had been paid to this condition, which resulted in an increased detection of NCC cases.…”
