There are several reasons why your pacemaker might stop working. You might have chest pain, difficulty breathing, dizziness, or lightheadedness. You can tell if your pacemaker is malfunctioning if you are starting to experience symptoms of arrhythmia.

Signs and Causes of Pacemaker Malfunction These pulses travel through the wires to the heart, helping the heart adjust its rhythm.

If the electrode detects an abnormal heartbeat, the computer tells the generator to create electrical pulses. The electrodes transmit this data through wires to a computerized, battery-powered generator. Pacemakers consist of electrodes that monitor your heartbeat. To avoid this, a pacemaker is used to correct abnormal heart rhythms. People with these conditions can struggle with getting enough blood pumped through the body, causing tiredness, difficulty breathing, or even fainting. This includes tachycardia, which is an unusually fast heart rate, and bradycardia, which is an unusually slow heart rate. How Your Pacemaker Helps Your HeartĪ pacemaker helps people with arrythmias. These devices are essential to patient health, so it is important to know if your pacemaker has stopped working and what to do about it. There are 3 million people living with pacemakers around the world, and 600,000 new pacemakers are implanted each year.

Electrophysiology Study: How EP Doctors Diagnose AFibĪ pacemaker is a device placed in your chest or abdomen that sends electrical pulses, helping the heart to beat at a normal rhythm.

Exit block results from changes in cardiac tissue over time (i.e.

Endocardium in contact with pacing lead requires higher stimulation threshold for conduction

Exit block: Failure of an adequate pacemaker stimulus to depolarize the chamber.

Definition: Pacemaker fails to sense native cardiac activity resulting in asynchronous pacing.

Treatment: replacement of single chamber pacemaker to dual chamber pacemaker.

Symptoms: Syncope/Near-syncope, orthostatic dizziness, exercise intolerance, generalized weakness, palpitations.

Occurs when there is intact sinus node function but atria contract with tricuspid/mitral valves closed (i.e.

Loss of AV synchrony and loss of atrial “kick”.

Pain, swelling, venous engorgement of the ipsilateral arm.

Occur in only 0.5 -3.5% of patients due to collateralization.

Common complication (30-50% with some venous obstruction) ( Kucher 2011).

Cardiology consultation for removal and replacement.

Needle aspiration: should only be performed under fluoroscopy to avoid cutting components of the device.

Blood cultures: (+) in 20-25% of patients (commonly S.

Signs/Symptoms: warmth, swelling, erythema, pain, fever.

An atrial event outside the refractory period will be inhibited.Device has a single lead in the ventricle that senses ventricular activity and can pace the ventricle.Sensory response: Can inhibit pacemaker in response to an intrinsic ventricular depolarization OR trigger pacemaker in response to an atrial intrinsic depolarization with no associated ventricular response.Chamber sensed: Intrinsic depolarization of the atrium and ventricle is sensed.Chamber paced: Atrium and ventricle can be paced.None (O): Does not trigger or inhibit regardless of the native activity.Dual (D): Dual inhibition of both atrial and ventricular pacing in response to intrinsic ventricular depolarization.Inhibited (I): Sensed intrinsic depolarization will result in inhibition of the pacemaker.

Triggered (T): Sensed intrinsic depolarization will result in the pacemaker discharging (this setting not used in current generation pacemakers).

First three letters are most useful in ED management.
