Prognostic significance of left anterior hemiblock
in patients with suspected coronary artery disease.
In our study the ECG abnormalities were sinus tachycardia, T-wave inversion in inferior leads, left anterior hemiblock
with left axis deviation and ventricular premature contraction.
Within the ECG abnormalities, repolarization abnormality (20%), tachycardia (12%), and left anterior hemiblock
(10%) were the most common.
Magni et al., "Limitations of the electrocardiographic diagnosis of left ventricular hypertrophy: the influence of left anterior hemiblock
and right bundle branch block," International Journal of Cardiology, vol.
Exclusion criteria were left ventricular hypertrophy, right ventricular hypertrophy, right and left bundle branch block, atrial flutter and fibrillation, anterior and posterior hemiblock
, paced rhythm, Wolff-Parkinson-White syndrome, and ventricular tachycardia or incomplete or erroneous data.
The patient's electrocardiogram (EKG) on admission revealed normal sinus rhythm with rate of 65 bpm (beats per minute) with first-degree atrioventricular block (AV Block) and left anterior hemiblock
as depicted in Figure 2.
Patients with CCC presented with typical electrocardiographic findings such as right bundle branch block and/or left anterior division hemiblock
, in addition to ventricular dysfunction classified on the basis of left ventricular ejection fraction <40%.
Left anterior hemiblock
and electrocardiographic diagnosis of left ventricular hypertrophy.
The 19 patients assigned to group II, Chagasic cardiomyopathy, (CDM) presented electrocardiographic abnormalities characteristic of either complete right bundle branch block plus anterior or posterior hemiblock
of the left bundle, or complete atrioventricular block with wide QRS complex (mean age 52 years; range 28 to 72 years).
Ackerman, prescribing pain medication was a departure and simply delayed the diagnosis by making the "evolution of the presentation of a heart attack." While at NYHQ the patient was markedly abnormal and showed left ventricular hypertrophy and left anterior hemiblock
, which Dr.
Also, electromechanical changes after ASA with the development of bundle branch block (right bundle branch block alone in 60% and with left anterior hemiblock
in 20%) lead to further inhomogeneity in LV contraction (78).
Serial electrocardiographic (ECG) recordings demonstrated dynamic anterior ST changes and T-wave inversions, a left anterior hemiblock
, and frequent ventricular premature beats.
