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

What can affect the exercise electrocardiogram results?

What can affect the exercise electrocardiogram results?

Certain medications: Certain medications obscure the ekg changes, or the exercise capacity reducing the utility of the test. Abnormalities of the resting ekg may also impair accuracy. Nuclear scans or echocardiographic images before and after exercise may be performed and may allow a diagnostic test even in these circumstances and also increase the diagnostic accuracy. ...Read more

I have an incomplete on an EKG reading what does it mean?

I have an incomplete on an EKG reading what does it mean?

Can't tell: Not sure what "incomplete" would be referring to if it's not associated with any other phrase. It may be followed by other information, e.g. Incomplete right bundle branch block. Might want to clarify. ...Read more

What does it mean when I have an irregular EKG reading during a sleep study?

What does it mean when I have an irregular EKG reading during a sleep study?

Arrhthmia: It could be atrial fibrillation, atrial flutter and pvcs. Treatment depends on what the monitored showed. Lot of times if your sleep apnea gets treated and if it improves, your arrhytmia will get better also. ...Read more

I had my EKG reading done in class today and my professor thought it was a little weird. The axis reading of P-QRS-T was -1,8, and -6. Is that weird?

Weird or not: P-wave axis normal is 0 to +75, QRS axis normal is -30 to +90, and T-wave axis normal is +15 to +75 degrees. QRS is normal. P-wave borderline and if you are younger lower atrial rhythm leading to an abnormal axis is not atypical if heart rate is slower. T-wave is ÔÇťabnormal" but falls within borderline zone. Number one cause of abnormal axis is incorrect lead placement. ...Read more

The ECG read it boarder line and the Doctor say it is within normal limit and to neglect the EKG reading.which one I should believe ?

The ECG read it boarder line and the Doctor say it is within normal limit and to neglect the EKG reading.which one I should believe ?

Doctor: Electrocardiograms take years of experience to interpret properly and even then there may be slight variables in each doctors assessment. With that being said, the doctor`s interpretation should be trusted. The computer makes broad generalizations and does not give conclusive results. ...Read more

Can you tell me if i had a normal EKG reading, but weeks after im still having chest pains should I worry about a heart attack?

Can you tell me if i had a normal EKG reading, but weeks after im still having chest pains should I worry about a heart attack?

Less likely: A nl ekg does not completely exclude active heart disease. If there are persistent symptoms cardiology eval with echo, stress test and cardiac enzymes may be in order. If these tests are neg and symptoms persist atrial of nsaids for costochondritismay be helpful. ...Read more

My EKG reading was 54, could that be the beginning of bradychardia? My mom has a slow heart beat and a heart murmur. I'm concerned I will get a murmur

My EKG reading was 54, could that be the beginning of bradychardia? My mom has a slow heart beat and a heart murmur. I'm concerned I will get a murmur

Bradycardia: Bradycardia in a person who is physically very active is normal. If you are performing aerobic exercise on a regular basis, do not worry about a heart rate of 54 bpm. A heart murmur can be benign, albeit if you develop it later in life, you need to be evaluated; however, there is very little correlation between bradycardia and a heart murmur (far-fetched correlations exist however). ...Read more

Is a 10 lead EKG machine as good as a 12 lead machine?

Is a 10 lead EKG machine as good as a 12 lead machine?

Depends: In some cases, a 3 or 5-lead ekg provides sufficient information. However, for a full picture of what the heart is doing, a 12-lead is the best. It takes 10 physical leads to produce a 12- lead ecg. Left and right arms, left and right legs, v1-v6. ...Read more

If i had hyperkalemia wouldn't it show peaked t waves throughout entire 12 lead EKG with widened qrs?

If i had hyperkalemia wouldn't it show peaked t waves throughout entire 12 lead EKG with widened qrs?

Depends: That is with life threatening hyperkalemia. If your case is mild, or chronic, it may not manifest yet with ekg abnormalities. ...Read more

What does an EKG 12-lead impression: non-specific st t wave abnormality mean?I i just need to know what this test result means.

What does an EKG 12-lead impression: non-specific st t wave abnormality mean?I i just need to know what this test result means.

A : A "nonspecific" abnormality means that the wave doesn't look like the typical, standard ekg. The st-t wave is the wave that occurs right after the qrs. Often times the wave doesn't look typical, but it is important to note if prior ekg's have appeared the same for the patient. Also, some medications can cause these changes. ...Read more

Meaning of the diagnosis from an EKG, 12 Lead, Initial: Sinus bradycardia, Low voltage QRS, Possible Septal and Inferior infarcts, age undetermined.

Meaning of the diagnosis from an EKG, 12 Lead, Initial: Sinus bradycardia, Low voltage QRS, Possible Septal and Inferior infarcts, age undetermined.

3 things: Sinus bradycardia means the heart rate is less than 60 Low voltage QRS could be associated with many things, including obesity, emphysema, lung disease, pericardial effusion, infiltrative cardiomyopathy, etc Possible septal and inferior infarcts age undetermined: there is some evidence of possible heart attacks on the septal and inferior walls of the heart, and cannot determine the age of events ...Read more

Why is it called 12 lead ecg if it only uses 10? Pls explain

The EKG is routinely: performed with 6 chest wires (V1-V6) (six signals or leads) and the four arm wires. 10 wires. The signals from the arm and leg wires are electronically combined to provide a triangular pattern of three leads (signals) I,II,III. And then also electronically combined to produce what is called augmented leads (signals). aVR, aVL, and aVF. 6 more signals (leads). Thus 10 wires and twelve leads. ...Read more

What is the indication for having a flat t wave in 12 lead ecg?

T Wave flattening : In the absence of clinical history or symptoms, t wave abnormalities such as flattened t waves are nonspecific. They may be seen in healthy individuals, leading to mistaken diagnosis of heart disease. Pathological causes are many & include myocardial ischemia, electrolyte abnormality, stroke, anticancer medications, and even with fever and after eating. Your dr, will tell you more. ...Read more
