Transient Left Bundle Branch Block: An Unusual Electrocardiogram in Takotsubo Cardiomyopathy

Transient mid-ventricular ballooning syndrome is a variant form of Takotsubo cardiomyopathy (TTC). The precipitating factors and clinical course are similar, and the clinical manifestations mimic those of acute coronary syndrome, which are characterized by transient left ventricular dysfunction without significant coronary artery disease. Takotsubo cardiomyopathy with transient left bundle bran...

To Perform Thrombolysis or Not: A Case of Acute Pancreatitis Presenting with Chest Pain and Transient Left Bundle Branch Block

A suspected case of acute coronary syndrome presented with new-onset left bundle branch and first-degree heart blocks. The decision to thrombolyse was reverted as ECG changes proved to be transient within fifteen minutes of presentation. Later on the patient was diagnosed with acute pancreatitis based on laboratory results of serum amylase, confirmed on radiological investigations.

Acute His Bundle Injury during Permanent His Bundle Pacing: Mechanistic Insights into Intra- Hisian Block

Permanent His bundle pacing (HBP) is a physiological alternative to right ventricular pacing. Acute injury to the His bundle can occur during permanent HBP in the form of transient or permanent bundle branch blocks. Observations of mechanical injury to the His bundle during HBP lead fixation and electrophysiological response to HBP provides additional mechanistic insights into the pathology of ...

His bundle recordings in patients with bundle branch block and transient neurologic symptoms.

Catheter-induced intra-Hisian and intrafascicular block during recording of His bundle electrograms.

or even complete A-V block. Two cases are reported in which catheter-induced transient high grade Mobitz II A-V block, acute reversible prolongation of infranodal conduction time with probable intra-Hisian conduction delay, and persistent (6 hours duration) complete A-V block occurred in patients with left bundle branch block. The observations made indicate that A-V conduction times and the app...
