CASE REPORT OF INSTALLATION OF PACEMAKER WITH LEFT
BRANCH ELECTRODES AT THE CARDIOLOGY DEPARTMENT OF
HOAN MY SAI GON HOSPITAL
Le Ha Trung
Hoan My Sai Gon Hospital
ABSTRACT
Background: A Pacemaker has been the treatment of symptomatic bradyarrhythmias
for more than six decades. Right ventricular pacemarker is the standard approach because
it is a proven safe and effective long-term procedure. Conduction system pacing by HIS
bundle and left bundle branch area pacing have recently developed as a preferred
alternative, having demonstrated considerable efficacy in correct left bundle branch block
and achieve cardiac resynchronization therapy.
Methods: Report 02 cases of 2-node pathology implanted with a pacemaker with left
bundle branch electrode at Cardiology Department, Hoan My Saigon Hospital.
Results: 02 cases were ≥ 60 years old, initial symptoms: palpitations, ECG results:
narrow QRS tachycardia and sinus pause 2 seconds after tachycardia or failure Sinus node
has pauses of more than 3 seconds and AV block is 2 at times. Both cases had chronic
diseases such as hypertension, dyslipidemia... Case 01 indicated that the patient should
wear the Holter ECG again (after 3 months) and recorded the syndrome of tachycardia and
bradycardia. There are indications for the use of drugs to slow the tachycardia and the
implantation of a pacemaker to prevent bradycardia. Case 2: The patient was implanted
with a 2-chamber pacemaker with the left bundle branch electrode at the beginning. Faster
site selection and less than 2 hours of procedure time. Both cases were consulted and
assigned to implant a pacemaker with a bundle branch electrode. Successful treatment
results, stable 6-month follow-up parameters.
Conclusion: At present, according to us, it is possible to consider indications in
complete atrioventricular blocks at risk of heart failure, atrial fibrillation due to ventricular
pacing, machine-dependent sinus node failure >40%, dual-chamber machine with
