Surgery arrhythmias

La cirugía de las arritmias más frecuente es el implante de marcapasos definitivo.

It is a surgical minimally invasive and low risk to the patient, and that improves the lives of people who suffer a heart rhythm disorder.

What is a pacemaker?

A pacemaker is an electronic device that conducts electrical impulses to stimulate the heart and get a contraction of the area stimulated when a fault occurs in the normal heart rhythm. It consists of a generator of electric pulses (the MCP itself) and one or more cables that carry that momentum through the cavities of heart (cables or electro-catheter).

How is implanted a pacemaker?

Using local anesthesia and a small incision in the area of the left clavicle. Guided by Rx, implanted an electrode, or two, to areas to the heart that we want to stimulate. Later, when the cable is in the proper place, is connected to the pacemaker, and it is housed under the skin.

Types of pacemakers

Single chamber

It consists of a generator and a single cable that stimulates and detects a single cavity heart, atrium or ventricle.

Bicameral

In this type of pacemaker, the generator is attached to two wires. One is located in the right atrium and the other in the right ventricle.

Tricameral or re-synchronizer

In this type of pacemaker, through the use of three electrodes, and for selected patients depending on situation, prior clinical and complementary tests, we get a sync on the contraction of the heart chambers.

Defibrillators, implantable

It is a device which has the function of a pacemaker, but adds to it the ability to detect the heart rate and apply a small electric shock to treat cardiac arrhythmias, malignant (ventricular tachycardias or ventricular fibrillation) that could lead to the death of the patient.
