Gann D, Balachandran PK, Sherif NE, Samet P (1975) Prognostic significance of chronic versus acute bundle branch
block in acute myocardial infarction.
Presence of T-wave changes or bundle branch
block (LBBB or RBBB) in this cohort of patients with CCHF predicted death with a sensitivity of 72.
Because left bundle branch
block and non-ischemic heart disease lead to diffuse, as opposed to localized, heart problems, study authors reasoned women were more responsive to CRT-D therapy, a treatment that strengthens the overall mechanical pumping action of the heart and coordinates the heart's electrical activity.
The three devices are intended to treat patients with left bundle branch
who have either mild heart failure or heart failure with no apparent symptoms.
The EKG was abnormal, showed tachycardia, right bundle branch
block, and Q wave abnormalities.
A 50-year-old head-injured patient with left bundle branch
block and neurogenic pulmonary oedema scheduled for urgent re-exploration and evacuation of large extradural haematoma developed broad complex ventricular tachycardia with hypotension five minutes after induction of anaesthesia.
Electrocardiography showed left bundle branch
block with diffuse changes in the ST segment and the T wave.
There have also been reports of prolongation of the QT interval, bundle branch
block, QRS prolongation and other EKG changes, ventricular tachycardia, bradycardia, hypotension, rhabdomyolysis, vertigo, liver necrosis, serotonin syndrome, and death.
Susan, an administration assistant, said: "Dale was diagnosed with a what doctors called a right bundle branch
block on his heart.
He said that the doctor told him he had a condition called bundle branch
An ECG can also be difficult to interpret in cardiac conditions, such as left bundle branch
block, ventricular paced rhythm, and left ventriculary hypertrophy.
