What segment of an ECG tracing represents the end of the atrial action potential?

What segment of an ECG tracing represents the end of the atrial action potential?

Ecg: The ecg represents the surface recording of electrical vectors produced by the summated electrical forces through time produced by the cells of the heart. As such there are millions of atrial action potentials summated in each portion. Roughly the end of the p wave and the rest of theQRS-T would correlate with atrial repolarization and depolarization would be present as the p wave appears ...Read more

Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

How dangerous is an ECG tracing- right nundle branch block septal wall ischemia for an 8 yo/ female child? She's having squeezing chestpain recently.

How dangerous is an ECG tracing- right nundle branch block septal wall ischemia for an 8 yo/ female child? She's having squeezing chestpain recently.

Possibly Dangerous: I am a pediatric cardiologist. I agree with the other answer--i would strongly recommend you take your child to see a pediatric cardiologist as soon as possible if you haven't already. The diagnosis of bundle branch block and ischemia is serious, but it depends where it is coming from. Machines are not good at interpreting pediatric ecgs. Again, please see a pediatric cardiologist asap. ...Read more

What do you mean by rbbb septal wall defect? This was the ECG tracing for my 8yo daughter, having on and off chestpain and palpitation.Gravity to her?

What do you mean by rbbb septal wall defect? This was the ECG tracing for my 8yo daughter, having on and off chestpain and palpitation.Gravity to her?

See cardiologist : Right bundle branch block (rbbb) is usually not a normal finding in a child although not always life threatening. If there is a history of ventricular septal defect repair, rbbb could be a benign finding. There are many other diagnoses which are associated rbbb. Further evaluation by a pediatric cardiologist is recommended. ...Read more

What is the 12. Lead ecg?

What is the 12. Lead ecg?

ECG: It stands for electrocardiogram. It is used to measure the movement of electrical signals in the heart. When working appropriately, this enables your heart to beat and pump blood to the rest of the body. When the heart is damaged or the electrical system is malfunctioning, ECG can pick up changes. ...Read more

Hi,can i send YOU my ecg?

Upload it: Ask tech support to help you upload it. Why at age 19 did you have to have an ECG. If you were having chest pains get a 2D ECHO FOR MITRAL PROLAPSE. Suggest trying magnesium 400 to 600 mg a day and Fish Oil 1000 mg 2x a day with meals ...Read more
