Understanding Ekgs Chapter 12 Introducing The Pacemaker Rhythms

Front 1

The parts of a artificial pacemaker

Back 1

The generator and the lead wires. The generator controls the rate and strength of each electrical impulse. The lead wires relay the electrical impulse from the generator to the myocardium.

Capture

Back 2

Noted by the presense of a spike and wide QRS complex, the presence of adequate femoral pulse, BP, and an increase level of consciousness.

Front 3

Atrial pacemaker

Back 3

The lead wire electrode is inserted into the right atrium. The pacemaker's electrical impulse first stimulates the atrium and then travels down the electrical conduction pathway through the ventricles.

Front 4

Ventricular pacemakers

Back 4

The lead wire electrode is inserted into the right ventricle. The electrical impulse from the pacemaker generator produces ventricular depolarization.

Front 5

AV sequential pacemakers

Back 5

The most common permanent pacemaker. There are two electrodes on the lead wire: one placed in the Rt atrium and one in the Rt ventricle, with impulses stimulating or pacing the atrial than the ventricles.

List common problems associated with pacemakers

Back 6

Battery failure, Runaway pacemakers, Failure to capture, and Failure of sensing devices in demand pacemakers.

>0.12 sec QRS
Use lead V1
Going back from P wave to QRS if it goes down it is a left if it goes up it is a right bundle branch block. Think of your cars turn signal.
