Postoperative Arrhythmia Medication Pearls | Hemodynamics at the Bedside

Postoperative arrhythmias rarely present as a rhythm strip alone.

The patient may be bradycardic and hypertensive, tachycardic because of bleeding or low cardiac output, in atrial fibrillation with marginal perfusion, or experiencing an arrhythmia complicated by pacing, electrolytes, ventricular dysfunction or recent cardiac surgery.

Postoperative Arrhythmia Medication Pearls helps clinicians think beyond the heart rate.

The guide combines rhythm recognition, hemodynamic assessment, medication considerations, pacing and escalation principles into a concise bedside reference for the cardiothoracic postoperative setting.

Current professional references include AHA adult bradycardia/tachyarrhythmia guidance, EACTS perioperative medication guidance and ACC/AHA/ACCP/HRS atrial fibrillation guidance.

• How blood pressure and perfusion change the significance of a rhythm
• Medication pearls and important cautions
• Electrolyte and reversible-cause assessment
• Temporary pacing considerations
• When cardioversion/defibrillation or immediate escalation may be required
• Common postoperative rhythm traps
