I was at the ER yesterday and was told that my EKG changed. Something about the QRS widening. What does that mean and how dangerous is it ? I have followed through with my Dr. via phone and he gave me the name of a cardiologist to see.
The parts of a QRS complexElectrocardiography (EKG, ECG) tracings show a characteristic pattern of electrical impulses that are generated by the heart. The QRS complex is a record of the measurement of the movement of electrical impulses through the lower heart chambers (ventricles), primarily in the Purkinje fibers

Hello, I am trying to sense a change in cardiovascular constriction due to emotional stress without measurements at any of the extremities (legs or arms) in an otherwise relaxed, sitting patient. Are there any indicators of cardiovascular constriction apparent in an EKG besides an increase in pulse rate? Thanks! Eric
I have ekg results that read: sinus rhythm, minor high-lateral repolarization disturbance, consider ischemia, LV overload or aspecific change, small negative T in aVL with flat or low negative T in 1, ECG without significant abnormalities. I am a 52 year old female and have a history of mitral valve prolapse. Can you please tell me in words I can understand, what these results indicate? Thank you. My name is Denise.

I am a 35 year old male, non-smoker, non-drinker, not overweight, and in pretty good shape healthwise. A year ago I had way too much caffeine after being off of it for several months, and my heart rate and blood pressure skyrocketed. Since then, I have had continuous (daily) discomfort on the far left side of my chest, close to the armpit. Sometimes it radiates around the left nipple, then goes away. It is not painful, just annoying. I do not have trouble breathing. I have gone to a cardiologist and had MRI, EKG, ECG, treadmill, x-rays, and bloodwork done. All are negative for cardiac. Any idea what might cause this? I am leaning toward anxiety of some kind, though I have never been diagnosed with anxiety.

have been having episodes of hypertension and cardiac pain. I spent Tuesday night in the ER getting blood work done, including a hs-CRP test which came back elevated at 7.4 mg/dL. I had a troponin test done that came back as slightly elevated (0.9 ng/mL). I also had an EKG which showed tachycardia (resting heart rate up into the 160s) as well as episodes of a-fib, and an echocardiogram which showed my left atrium was significantly thickened/larger than expected for a normal twenty year old. I was admitted to the cardiac unit over night for observation and given nitroglycerin for the pain as well as medication for my blood pressure. The blood pressure levels regulated somewhat, going down to average of 138/95 at discharge. They gave me a preliminary diagnosis of angina which is shocking since I m 20, of normal weight, have a healthy diet, and normal cholesterol. I ve been referred to a cardiologist and am scheduled for a stress test on Monday. What should I expect? What will the stress test show? Also, what does a enlarged left atrium mean? Is it serious? thanks!
