The following are examples of typical codes: There is a 5-position code, of which the first 3 letters are the most relevant to the EM physician. Pacer codes describe the function of the pacemaker.

AICD will have a thick coil that differentiates it from a pacemaker (as seen in AICD PA and Lateral Views).A common fracture site is between the first rib and the clavicle.

Leads (number, location, and continuity).

Failure to capture pacemaker generator#

Compare pulse generator location with a prior CXR if available.

Manufacturer code, which is found on pulse generator.

A chest x-ray should be obtained to evaluate for:

Pocket hematoma (bleeding associated with facial plane dissection for pocket creation)ДЄll cardiac pacemakers consist of a pulse generator and at least 1 lead connecting the generator to the myocardium.

Venous thrombosis of the upper extremity.

CHF with electromechanical ventricular dyssynchronyДЄlthough relatively rare, complications from pacemaker implantation typically occur within the first 6 weeks of placement and include:.

For sustained pause dependent VT, with or without QT prolongation.

Recurrent syncope caused by spontaneously occurring carotid sinus stimulation and carotid sinus pressure that induces ventricular asystole of > 3 seconds.

Symptomatic chronotropic incompetence (failure to achieve 85% of age-predicted maximal heart rate during formal or informal stress test or inability to mount age appropriate heart rate during activities of daily living).

Some of the Class I indications for pacemaker insertion per the 2012 ACCF/AHA/HRS guidelines 3 include:

Toxicity in these patients may present with pacemaker ventricular capture latency or failure to capture.Can you distinguish between an abnormal EKG and a cardiac device malfunction at a glance, recall common pacer codes, or identify pacemaker problems on an X-ray?ДЄs the use of cardiac devices increases, 1-2 emergency physicians must know how to manage not only patients who may need a pacemaker, but also those who present to the ED with a device already implanted.В This article summarizes the indications for pacemaker insertion, evaluating a pacemaker on a chest X-ray, understanding pacer codes, interpreting normal and abnormal EKG findings with paced rhythms, and pacer malfunctions. The flecainide level drawn on arrival was 3.09 mcg/mL.Д¬ONCLUSIONS: Flecainide increases the ventricular capture threshold for pacemakers. After multiple boluses of IV sodium bicarbonate, the QRS acutely narrowed, latency interval improved, and consistent pacing capture was achieved. The pacemaker was interrogated, revealing a significant increase in ventricular threshold from 0.75 V at 0.5 ms at baseline to 5.0 V at 1 ms to obtain consistent capture. A 12-lead ECG demonstrated atrial and ventricular pacing with severely widened QRS complex and a significant latency between the pacemaker ventricular spike and the ventricular capture. Lab work was notable for creatinine at 2.12 mg/dL. She was found to be hypotensive and bradycardic, with a heart rate between 30 to 40 beats per minute. We describe a unique case of flecainide toxicity secondary to acute kidney injury in the setting of a dual-chamber pacemaker, resulting in ventricular capture latency and intermittent failure to capture.Д¬ASE REPORT: The patient was a 91-year-old female with a history of atrial fibrillation maintained in sinus rhythm on flecainide, who presented complaining of purple visual disturbances and syncope. It is associated with a potent adverse effect profile however, the effects of flecainide toxicity in the setting of a pacemaker have not been well described. BACKGROUND: Flecainide is a class Ic antiarrhythmic agent used in the treatment of supraventricular and ventricular arrhythmias.
