Episode notes
Why Episode Was Split In Two
- The hosts split narrow and broad complex topics across episodes because narrow took an hour and they couldn't record longer.
- Rob joked about practicing introductions in a mirror and setting it as a ringtone for family.
Definition And Origins Of Broad Complex Tachycardia
- Broad complex tachycardia is defined by rate >100 bpm with QRS >0.12s and often originates from the ventricles.
- Not all broad complexes are ventricular; some atrial rhythms with aberrant conduction can also widen the QRS.
Common Causes Of Ventricular Tachycardia
- Ischaemic heart disease is the commonest cause of ventricular tachycardia, but structural disease, channelopathies and infiltrative disease also contribute.
- Electrolyte disturbance, drugs and myocarditis are additional important precipitants to consider.
