How is Dextrocardia diagnosed on ECG?

How is Dextrocardia diagnosed on ECG?

ECG Features of Dextrocardia

  1. Right axis deviation.
  2. Positive QRS complexes (with upright P and T waves) in aVR.
  3. Lead I: inversion of all complexes, aka ‘global negativity’ (inverted P wave, negative QRS, inverted T wave)
  4. Absent R-wave progression in the chest leads (dominant S waves throughout)

What are the criteria for Wolff-Parkinson-White Syndrome?

Classic ECG findings that are associated with WPW syndrome include the following: Presence of a short PR interval (<120 ms) A wide QRS complex longer than 120 ms with a slurred onset of the QRS waveform, termed a delta wave, in the early part of QRS.

What are the ECG characteristics of Wolff-Parkinson-White Syndrome?

The classic ECG morphology of WPW syndrome is described as a shortened PR interval (often <120 ms) and a slurring and slow rise of the initial upstroke of the QRS complex (delta wave; see the image below), a widened QRS complex with a total duration greater than 0.12 seconds, and secondary repolarization changes …

Is dextrocardia harmful?

Some people with isolated dextrocardia have an increased risk of lung infections, sinus infections, or pneumonia. With isolated dextrocardia, the cilia in your lungs may not function normally. Cilia are very fine hairs that filter the air you breathe.

Where do you put dextrocardia leads?

Dextrocardia occurs when the heart is positioned in the right side of the chest instead of the left. The ECG findings include: Predominantly negative P wave, QRS complex, and T wave in lead I. Low voltage in leads V3-V6 (since these leads are placed on the left side of the chest).

Can you be misdiagnosed with WPW?

The WPW pattern can be misdiagnosed, and false-positives from ECG on exercise are common. Electrophysiological study is the most reliable method of establishing the prognosis of WPW syndrome. The study can be performed by the transoesophageal13 or intracardiac route.

What is the typical ECG finding for WPW?

Wolff-Parkinson-White (WPW) Syndrome ECG Review. The typical ECG finding of WPW is a short PR interval and a “delta wave.“ A delta wave is slurring of the upstroke of the QRS complex. This occurs because the action potential from the sinoatrial node is able to conduct to the ventricles very quickly through the accessory pathway,…

What are the findings of a dextrocardia ECG?

Dextrocardia ECG Review. Dextrocardia occurs when the heart is positioned in the right side of the chest instead of the left. The ECG findings include: Predominantly negative P wave, QRS complex, and T wave in lead I. Low voltage in leads V3-V6 (since these leads are placed on the left side of the chest).

How is WPW syndrome related to atrial fibrillation?

Wolff-Parkinson-White (WPW) Syndrome ECG Review. Therefore, patients with WPW who develop atrial fibrillation have higher ventricular rates than those without WPW. If an AV blocking agent is given, fewer atrial action potentials will pass through the AV node, and more will pass through the accessory pathway.

When to refer a patient to cardiology for WPW?

Prompt referral to cardiology is essential for risk stratification through electrophysiological studies. Wolff-Parkinson-White syndrome (WPW) is the commonest form of ventricular pre-excitation.
