What is Dextroposition of the heart?

Dextroposition describes a heart on the right with an apex to the left, secondary to extracardiac causes (right lung hypoplasia, pneumonectomy or diaphragmatic hernia). In contrast, dextrocardia results from cardiac chamber disarrangement.

Where do you put ECG leads for dextrocardia?

Similar to a right-sided ECG, use the same physiological landmarks to place the 12-lead electrodes on the right side of the chest. Another consideration for treatment is the placement of pacer or defibrillator pads.

How do you take an ECG in dextrocardia?

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).

Do you reverse limb leads with dextrocardia?

ECG Features of Dextrocardia These changes can be reversed by placing the precordial leads in a mirror-image position on the right side of the chest and reversing the left and right arm leads.

What does Levocardia mean?

Strictly speaking, levocardia means that the cardiac apex is left sided. Isolated levocardias are those hearts that are left sided when situs inversus is present. This anomaly occurs in less than 1% of all patients with congenital cardiac malformation compared with a 2% incidence of dextrocardia in patients with CHD.

How do you do right-sided ECG?

Right-sided leads

  1. A complete set of right-sided leads is obtained by placing leads V1-6 in a mirror-image position on the right side of the chest (see diagram below)
  2. It may be simpler to leave V1 and V2 in their usual positions and just transfer leads V3-6 to the right side of the chest (i.e. V3R to V6R)

Can ECG detect dextrocardia?

In addition, reorientation of the precordial leads to a right-sided approach (leads V1R–V6R) results in a typical pattern of septal depolarization and R-wave progression on the 12-lead ECG. 6,8 To our knowledge, current ECG machines do not have algorithms to detect dextrocardia.
