IV Push Dosing for Symptomatic Sinus Tachycardia

Assessment and Initial Management

The American College of Cardiology recommends evaluating for physiologic causes of sinus tachycardia, such as fever, anemia, hypotension, shock, pain, anxiety, medications, and recreational drugs, before initiating specific treatment in patients with symptomatic sinus tachycardia 1, 2
The American Heart Association suggests providing supplementary oxygen if the patient shows signs of increased work of breathing or inadequate oxygenation 1
The American College of Cardiology advises establishing IV access, attaching a cardiac monitor, and obtaining a 12-lead ECG to confirm sinus tachycardia in patients with suspected symptomatic sinus tachycardia 1
The American College of Cardiology recommends determining if the patient is hemodynamically stable or unstable in patients with symptomatic sinus tachycardia 1

The American College of Cardiology recommends immediate synchronized cardioversion for patients with rate-related cardiovascular compromise due to sinus tachycardia, characterized by signs of acute altered mental status, ischemic chest discomfort, acute heart failure, hypotension, or shock 1
The American Heart Association suggests using an initial energy of 50-100 J with biphasic waveform for synchronized cardioversion of sinus tachycardia in hemodynamically unstable patients 1
The American College of Cardiology advises increasing the dose in a stepwise fashion if the initial shock fails to convert the rhythm in patients with symptomatic sinus tachycardia 1

The American College of Cardiology recommends identifying and treating the underlying cause of sinus tachycardia rather than directly suppressing the sinus node in hemodynamically stable patients 1, 2, 3
The American Heart Association notes that when cardiac function is poor, cardiac output may be dependent on a rapid heart rate, and "normalizing" the heart rate can be detrimental in such cases 1
The American College of Cardiology suggests that beta blockers are effective for physiological symptomatic sinus tachycardia triggered by emotional stress, anxiety disorders, and post-myocardial infarction 2, 3
The American College of Cardiology recommends considering non-dihydropyridine calcium channel blockers, such as diltiazem, as an alternative to beta blockers in patients with symptomatic sinus tachycardia 3
The American College of Cardiology notes that ivabradine is an effective agent for ongoing management of inappropriate sinus tachycardia, although it is not available as an IV push 5

The American College of Cardiology recommends beta blockers as first-line therapy for inappropriate sinus tachycardia, despite modest efficacy 5
The American Heart Association advises avoiding rate control medications in compensatory tachycardia where cardiac output depends on the rapid heart rate 1
The American College of Cardiology recommends avoiding calcium channel blockers in patients with suspected systolic heart failure or ventricular tachycardia 4
