If it is necessary to pace for more than 30 minutes, periodic inspection of the underlying skin is strongly advised." It is meant to stabilize the patient until a more permanent means of pacing is achieved. Other forms of cardiac pacing are transvenous pacing, epicardial pacing, [5] and permanent pacing with an implantable pacemaker.
The difference between pacemakers and ICDs is that pacemakers are also available as temporary units and are generally designed to correct slow heart rates, i.e. bradycardia, while ICDs are often permanent safeguards against sudden life-threatening arrhythmias.

Percussive pacing, also known as transthoracic mechanical pacing, is the use of the closed fist, usually on the left lower edge of the sternum over the right ventricle in the vena cava, striking from a distance of 20 – 30 cm to induce a ventricular beat (the British Journal of Anaesthesia suggests this must be done to raise the ventricular pressure to 10–15 mmHg to induce electrical activity).
In the United Kingdom (UK) the WCD LifeVest® from ZOLL is available for temporary use on a monthly rental basis since 2017. [15] The WCD is a temporary therapeutic option for patients waiting for an ICD, patients with an ICD that had to be removed (e.g., due to infection), or patients who can't have an ICD but are at transient risk for SCD. [16]
Patients who are relatively older, who need ICD for secondary prevention, or who have concomitant bradycardia requiring pacing, or heart failure requiring cardiac resynchronisation therapy are more suitable for transvenous ICD implantation. An older patient with ischemic cardiomyopathy and documented symptomatic ventricular tachycardia is a ...
The pacing electrode is advanced through the vein under fluoroscopic and electrocardiographic guidance. An X-ray after the procedure is always obtained to confirm placement of the pacing electrode. The greater use of atropine and epinephrine or external pacing may make transvenous pacing unnecessary by stabilizing patients early in the process ...

VADs can further be divided by the duration of their use (i.e. temporary versus permanent). Some VADs are for short-term use, [ 3 ] typically for patients recovering from myocardial infarction (heart attack) and for patients recovering from cardiac surgery ; some are for long-term use (months to years to perpetuity), typically for patients with ...
