Most cases of dextrocardia are diagnosed using an electrocardiogram Electrocardiography is the process of producing an electrocardiogram, a recording – a graph of voltage versus time – of the electrical activity of the heart using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle. Changes in the normal ECG pattern occur in numerous cardia…Electrocardiography
What are the ECG features of dextrocardia?
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).
How do you test for dextrocardia?
Electrocardiogram (ECG/EKG). Heart MRI. Your provider may recommend genetic testing and other tests to check for syndromes. An electrocardiogram (ECG/EKG) reading can show if you have dextrocardia. ECG tests create a picture of your heart’s electrical activity, which has a normal graph when the heart is in its normal location on the left.
What is dextrocardia and how is it treated?
Dextrocardia is a rare congenital heart condition in which your heart is in the right side of your chest and points to the right. Typically, your heart is on your left side and points to the left. Dextrocardia only needs treatment if other heart issues or genetic syndromes are causing problems. Surgery may be needed depending on the issues.

What is the difference between dextrocardia and Dextroposition?
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.

What is the difference between situs inversus and dextrocardia?
Disease at a Glance In people affected by dextrocardia, the tip of the heart points towards the right side of the chest instead of the left side. Situs inversus refers to the mirror-image reversal of the organs in the chest and abdominal cavity. Some affected people have no obvious signs or symptoms.
What happens if ECG leads are put on incorrectly?
The analysis of ECG signals recorded from misplaced electrodes can lead to misinterpretation or even to significant diagnostic errors like incorrect recognition of anterior infarction, anteroseptal infarction, ventricular hypertrophy [9, 14], false diagnosis of ischemia, or Brugada syndrome [16, 24].

Why does dextrocardia cause intestinal malrotation?
This is because dextrocardia can sometimes result in a condition called intestinal malrotation, in which your gut doesn’t develop correctly. For that reason, your doctor will watch out for an abdominal obstruction, also called bowel or intestinal obstruction. An obstruction prevents waste from leaving your body.

Isolated dextrocardia usually causes no symptoms. The condition is usually found when an X-ray or an MRI of your chest shows the location of your heart on the right side of your chest.
Does dextrocardia occur during fetal development?
Researchers do know that it occurs during fetal development. The heart’s anatomy may have many variations. For example, in isolated dextrocardia, your heart’s completely intact but faces the right side instead of the left. In other forms of dextrocardia, you may have defects in the heart’s chambers or valves.
What is the process of dextrocardia?
Dextrocardia occurs as a result of abnormalities in the embryological development of the heart. The heart is the first organ to develop in an embryo. The fetal heart develops from an embryonic heart tube, which is formed by the fusion of the endocardial tubes. The heart tube attaches to the cranial aspect to the arterial trunk, and the caudal aspect is connected to the venous channels. Once the heart tube is formed, the next important step in the development of the heart is looping. Looping determines the position of the ventricle in relationship to the atria. The heart tube may loop to the right (termed as D loop) or loop to the left (termed as L-loop). With a D-loop, the morphologic right ventricle lies to the right of the left ventricle, whereas, with an L-loop, the morphologic right ventricle is positioned to the left of the left ventricle. [10][11][12] If a D-bulboventricular loop fails to migrate into the left hemithorax, it can result in dextrocardia with the heart in the right hemithorax. Similarly, if an L-bulboventricular loop completes the rotation in the right hemithorax, the heart can be situated in the right hemithorax. It is not entirely clear the circumstances leading to these aberrations in embryonic development; however, an association with a defect in dynein or ciliary motility has been implicated. [13]

What test is used to diagnose Kartagener syndrome?
Nasal brush biopsy and nasal nitric oxide measurements are screening tests used to diagnose Kartagener syndrome.[20] CT scan of the chest might reveal bronchiectasis and dextrocardia in these patients.
