Although, precordial thump is relatively ineffective for
ventricular fibrillation, and it is no longer recommended for this rhythm. A precordial
thump should be considered if cardiac arrest is confirmed rapidly following a
witnessed and monitored (ECG) sudden collapse (VF or VT) if the defibrillator
is not immediately at hand.
There is insufficient evidence to recommend for or
against the use of the precordial thump for
witnessed onset of asystole caused by AV-conduction
disturbance.
The precordial thump should not be used for unwitnessed
cardiac arrest.
A precordial thump should not be used in patients with
a recent sternotomy (eg. for coronary artery grafts or valve replacement), or recent chest trauma.
