Differential Diagnosis
- Single most likely diagnosis
- Atrial Tachycardia: This is the most likely diagnosis given the explicit mention of atrial tachycardia in the analysis. The presence of low burden PACs and PVCs, along with NSVT, supports the idea that there is an abnormal heart rhythm, and atrial tachycardia is directly stated.
- Other Likely diagnoses
- Sinus Tachycardia: Given that triggered events correspond to sinus rhythm, it's possible that the patient experiences periods of sinus tachycardia, especially if the atrial tachycardia is paroxysmal.
- Anxiety or Stress-related Cardiac Symptoms: The presence of PACs, PVCs, and NSVT can sometimes be associated with anxiety or stress, which might not be directly related to a structural heart disease but could explain some of the findings.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Cardiac Ischemia or Infarction: Although not directly suggested by the findings, cardiac ischemia or infarction can sometimes present with arrhythmias, including atrial tachycardia, and would be critical to rule out due to their potential severity.
- Wolff-Parkinson-White (WPW) Syndrome: This condition can cause atrial tachycardias and is important to diagnose due to its potential for leading to more dangerous arrhythmias.
- Rare diagnoses
- Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC): A rare condition that could potentially cause ventricular arrhythmias, including NSVT, though it's less directly linked to atrial tachycardia.
- Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT): A rare genetic disorder that can cause ventricular arrhythmias, including NSVT, often triggered by physical activity or emotional stress.
