Cardiology: Stokes-Adams attack — Pacemaker implantation. Treatment
Morgagni-Adams-Stokes (MAS) Syndrome is called the loss of consciousness due to acute cardiac conduction disturbance. During bouts, the patient receives CPR. To prevent recurrence, the physician may recommend implanting a pacemaker.
Indications and Contraindications
The basis for device installation is the presence of the patient's bradycardia caused by sinus or atrioventricular block of grade 2 to 3.
Surgeries are not carried out, if the patient was diagnosed with paroxysmal tachycardia or atrial tachyarrhythmia.
Why Do I Need a Pacemaker?
A pacemaker helps upon slow heart rate or pauses in the work of the heart. The device continuously monitors the heart muscle contractions. As soon as their frequency slows, it generates its own electronic pulses and sends the same to the myocardium. If there is no contraction at all, the device starts producing a continuous signal at a set frequency. This ensures the maintenance of normal heart activity. The brain is supplied with blood in the right amount, and it eliminates the repetition of MAS attacks.
Under local anesthesia, the surgeon makes an incision under the patient’s collarbone. Then, s/he brings electrodes through a vein to the chambers of the heart and implants them into the wall. The correctness of manipulations is monitored by radiography.
After verification of electrodes, they are connected to the main unit, which is sutured under the skin. The intervention takes 1.5 to 2 hours.
After surgery, the patient is transported to the intensive care unit. Hospitalization duration can vary from 1 to 5 days in different cases. Initially, the patient feels the implant beneath the skin, but gradually this discomfort passes.
Full recovery may take 1 to 2 months. Periodically, the patient must undergo check-ups at the heart surgeon. During the visits, the expert verifies proper operation of the device and makes adjustments, when required. The check-ups are absolutely painless for the patient, since the information is read from the device remotely.
The service life of the pacemaker depends on how often it must generate the pulses, but on the average it is 5 to 10 years. The battery runs out for a few months, so the physician has enough time to replace it.Hide
