The article was written by specialist doctor II To Van Thai - Emergency Resuscitation Department - Vinmec Hai Phong International General HospitalA temporary pacemaker is an artificial device that generates periodic, 1-way electrical pulses that stimulate the heart muscle to periodically contract at the desired frequency.
1.Temporary pacemaker function
Today's temporary pacemakers are capable of:
Analyze the functional activities of the electrical system of the heart. When necessary, the machine will generate supportive impulses to ensure the functioning of the heart. Recently, a number of new indications for pacemakers have been added, such as in the treatment of heart failure, in hypertrophic cardiomyopathy with left ventricular outflow tract obstruction, in some tachyarrhythmias, etc.
2. Methods of temporary pacemaker
Percutaneous pacing: Electrodes placed on the skin, the procedure is quick, easy to perform, but has a low success rate (78-94%), can be performed while waiting for IV placement. Esophageal electrode pacing: The electrode is placed into the lower esophagus, the electrode is not fixed, this procedure is rarely used in emergency because it does not guarantee atrioventricular conduction.

Intravenous pacing: The electrode is usually inserted through one of the posterior subclavian, internal jugular, or femoral veins, which is a reliable method, but may cause ventricular arrhythmias during the procedure and pneumothorax and overflow. pleural blood, ... However, this is the most applied method in cardiology departments. Transepicardial pacing (Electrodes placed in the epicardium during cardiac surgery).
3. Indications and contraindications for temporary pacemaker placement in the emergency room
3.1 Indications Symptomatic bradycardia arrhythmias such as:
Symptomatic sinus node failure Sinus arrest Sinus bradycardia Symptomatic atrioventricular block II degree atrioventricular block, Mobitz II degree III atrioventricular block Symptomatic bradycardia drug poisoning symptoms

In addition, prophylaxis can be considered to prevent bad, rapid, life-threatening situations: arrhythmia in patients with myocardial infarction, myocarditis, ...
3.1 Contraindications Stable Asymptomatic bradycardia with stable escape rhythm Bradycardia without danger signs Severe infection at site Severe coagulopathy
4. Complications
Pneumothorax
Perforation causing hemopericardial arrhythmias More severe arrhythmias Machine-induced arrhythmia Complications at puncture site: Hematoma at puncture site Infection complications at insertion site, embolism Gas, venous thrombosis, Vinmec International General Hospital is one of the hospitals that not only ensures professional quality with a team of leading medical doctors, modern equipment and technology system.
