Background
Clinical Features
- Palpitations
- non-specific finding
- associated with all tachydysrhythmias, not just AT
- rapid fluttering/throbbing/pounding sensation in the chest or neck
- Syncope
- patients with AT rarely present with syncope
- cerebral hypoperfusion is more common with a ventricular rate >200 bpm
- Chest pain
- can present if there is underlying cardiovascular disease
- represents a worsening of the associated disease
- Dyspnea
- can present if there is underlying cardiovascular disease
- represents a worsening of the associated disease
Differential Diagnosis
Narrow-complex tachycardia
- Regular
- AV Node Independent
- Sinus tachycardia
- Atrial tachycardia (uni-focal or multi-focal)
- Atrial fibrillation
- Atrial flutter
- Idiopathic fascicular left ventricular tachycardia
- AV Node Dependent
- AV Node Independent
- Irregular
- Multifocal atrial tachycardia (MAT)
- Sinus tachycardia with frequent PACs, PJCs, PVCs
- Atrial fibrillation
- Atrial flutter with variable conduction
- Digoxin Toxicity
