Main Ideas - Palpitations Overview
Palpitations are a common symptom and can be benign but may indicate serious underlying issues. Understanding the patient's history, typical presentations, and red flag symptoms is crucial. Differentiating between causes, including ectopic beats, supraventricular tachycardias like AVNRT and AVRT, and atrial fibrillation, aids in tailored management.
Symptom Correlation & Investigations
Rhythm symptom correlation is vital in diagnosing palpitations. Ambulatory cardiac monitoring devices like Holter monitors or cardiac loop recorders can help capture symptoms during ECG readings. Lab tests for blood counts, electrolyte levels, and thyroid function, along with imaging techniques like echocardiograms and cardiac MRIs, are useful in diagnosing underlying conditions.
ECG Analysis & Potential Diagnoses
Analyzing a 12-lead ECG for signs of ischemic or structural heart disease, long QT syndrome, Brugada syndrome, and arrhythmogenic cardiomyopathy can aid in diagnosis. Specific ECG findings like ST or T-wave changes, QT interval abnormalities, and right ventricular ECG patterns signal potential serious arrhythmias.
Management Strategies
Management of palpitations varies based on the underlying cause. Ectopic beats may be controlled with beta blockers or require ablation. Supraventricular tachycardias like AVNRT and AVRT often benefit from ablation. Atrial fibrillation and flutter focus on anticoagulation and symptom management, with more complex cases possibly requiring ablation. Ventricular tachycardias necessitate cardiology consultation for appropriate management.
Conclusion and Podcast Wrap-up
The episode delves into palpitations, their differential diagnoses, diagnostic approaches, and tailored management strategies. It emphasizes the importance of understanding ECG findings, conducting thorough investigations, and implementing precise management plans to address various causes of palpitations.
Sam welcomes Dr Alex Carpenter, cardiology registrar with a specialist interest in electrophysiology to tackle the topic of palpitations. This is such a common topic with tons of clinical crossover and we discuss the common causes of palpitations, how they typically present and how you can tease this out in your history. We also talk through how to strategise the investigation of your patients and the various types of ambulatory ECG monitoring.
