Total surgical repair of TOF is a curative surgery. Different techniques can be used in performing TOF repair. One method to permit pulmonary blood flow post-birth is the stenting of the ductus arterious (DA) through the inducement of a systemic-to-pulmonary shunt. This surgical approach has an 83% success rate.
Congenital heart defects are the most common birth defect. [3] [11] In 2015, they were present in 48.9 million people globally. [8] They affect between 4 and 75 per 1,000 live births, depending upon how they are diagnosed. [3] [12] In about 6 to 19 per 1,000 they cause a moderate to severe degree of problems. [12]
Long QT syndrome (LQTS) is a condition affecting repolarization (relaxing) of the heart after a heartbeat, giving rise to an abnormally lengthy QT interval. [7] It results in an increased risk of an irregular heartbeat which can result in fainting, drowning, seizures, or sudden death. [1]
But this negative flow causes a positive T wave; although the cell becomes more negatively charged, the net effect is in the positive direction, and the ECG reports this as a positive spike. [2] However, a negative T wave is normal in lead aVR. Lead V1 generally have a negative T wave.
The cause of congenital third-degree heart block in many patients is unknown. Studies suggest that the prevalence of congenital third-degree heart block is between 1 in 15,000 and 1 in 22,000 live births. [citation needed] Hyperkalemia in those with previous cardiac disease [8] and Lyme disease can also result in third-degree heart block. [9]

Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.
