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

Would you take an antiarrhythmic drug to maintain normal sinus rhythm?

I had an ECG, exercise stress ECG, 48-hr holter ECG, and an echo. Would prolonged QT show up on all of those tests?

I had an ECG, exercise stress ECG, 48-hr holter ECG, and an echo. Would prolonged QT show up on all of those tests?

Majority: Yes, if you are concerned for prolonged QT or there is a family history, all of those tests except for an echo should show prolonged QT syndrome. An echo measures the function of the heart. Prolonged QT is calculated from an ECG looking at the part of the heart that makes up the QT interval in the heart beat. An ECG, stress ECG and Holter ECG should be able to pick it up. ...Read more

Indications for an ICD? I had a 15 beat run of self-terminating polymorphic VT. Normal cardiac MRI with Non family history & normal baseline ECG.

Indications for an ICD? I had a 15 beat run of self-terminating polymorphic VT. Normal cardiac MRI with Non family history & normal baseline ECG.

Cardiologist: A cardiologist is best qualified to evaluate and advise you as well as order outpatient holter monitor, cardiac stress test, magnesium and potassium blood levels and echocardiogram. If these are all normal or negative for recurrent ventricular irritability, no treatment or maybe a beta blocker may be prescribed. If frequent vpb's are seen, an cardiac ep specialist will be recommended for evaluatio ...Read more

I was prescribed two med lopressor (metoprolol tartrate) from a cardiolist and methimazole for hyperthyroidism. Not taking them I have an appointment with a endorc. Outcome?

Told to take meds: ...Is the likely outcome. That pair of meds is used when thyroid levels are high, making metabolism run high, with risk of heart attack, arrhythmia, stroke.

Should i stop taking mirtazapine before my 24 hour pH test/manometry? Can you recommend an antidepressant without an antiacid effect?

Should i stop taking mirtazapine before my 24 hour pH test/manometry? Can you recommend an antidepressant without an antiacid effect?

Ask your doctor: Ask the doctor ordering the test what s/he wants you to do. Gastric parietal cells respond to at least 3 triggers to secrete stomach acid: gastrin, acetylcholine (muscarinic receptors), and histamine (h2 receptors). You're also on cimetadine. Mirtazepine does have a strong antihistaminic and some anticholinergic effects. Fluvoxamine ; venlafaxine are reportedly devoid of these effects. ...Read more

This is usually transposable to heart rate. The holter is a 24 hour ECG recording. An r-r interval of 1second equates to a heart rate of 60 beats per minute. ...Read more

For slight murmurs, is it appropriate to get an EKG or an echocardiogram?
