The EKG is a graphical representation of electrical impulse wave moving through the heart - think of having a sharpie marker attached to a buoy floating in some body of water - a wave goes by, moves the pen making a representational two-dimensional mark on a piece of paper. Now you have a three dimensional event (a wave moving a buoy), represented by a two-dimensional mark.
So this is in essence what an EKG does - it measures the rate, size, and direction that the electrical impulse as it spreads through the heart. All of the different tracings are just views coming from another direction (pens attached to all four sides and the top of the buoy, if you will)
Now that you have a basis to understand what an EKG does -lets define specifically that read out.
introventricular conduction delay - The ventricle is the lower part of the heart. Intro = within. Conduction delay is something that inhibits the electrical impulse from moving as rapidly as it would be expected.
Nonspecific - related to a noted difference that does not fit a pattern of a known disorder. It may look similiar to something but does not deflect enough or in as many leads as necessary to meet a certain strict criteria.
Leftward axis - It is expected that the tracing will deflect in a certain manner. When it deflected in a different manner the two dimensional representation "leans" to the left or right under certain criteria. It means that the impulse is traveling through the heart rather than top right to bottom left, top middle or top left to bottom right. It can indicate certain things (like cardiac injury) or nothing (normal variant). It is highly dependent on the context.
ORS complex is the largest deflection on the EKG. It is a graphical representation the ventricle depolarizing (contracting) as the left ventricle is the most muscular part of the heart and therefore generates the largest electrical impulse.
Does this mean anything serious? I doubt it, but as I mentioned it depends on the context. If these finding are new - that is, there are other EKG tracings without the above findings, then yes, it does mean something. If it is just a read out on a first time EKG with no specific symptoms or positive lab studies, it probably means nothing.
I hope that helps. Good luck.

What does it mean if my heart beats about 90 times a minute on average? Even when I m calm and not doing anything, my heart beats pretty quickly. I ll notice it when I m watching TV or laying down to go to sleep. What does it mean? Am I gonna die soon? I forgot to mention I m not fat. If anything I m underweight. I workout regularly too. And I m 17
Hello Doctor, I want to ask you that what is the average thickness of endometrial during a normal month cycle if I am not pregant. Me & my husband have been trying for an year to have a baby & I am not sure if I am pregnant or not. The thickness of my endometrial is 13.5 mm does it mean I can be pregnant as I have heard normally during a month the endometrial thickens uptill 8mm only. I am confused, I would be thankful if you can clear me this doubt. Thanks you & have a nice day.
I recently had an ECG after an abnormal EKG. The ECG showed vent. rate 108bpm Sinus tachycardia, PR interval 158 ms, possible left atrial enlargement, QRS duration 88 ms , nonspecific ST abnormality, QT/QTc 368/493 ms, abnormal ECG, P-R-T axes 70 48 58 and prolonged QT. The cardiologist didn t seem very concerned and felt the abnormality was because of the medication I was taking - remeron for sleeping; I suffer from chronic insomnia. I have been on this medication for over two years and have never had any side effects or problems with it. In the past three-four months, however, I have been experiencing chest pains, some severe which is why I went to my physician to get the first EKG which showed a fast heart beat and was referred to the cardiologist for an ECG, EKG and a stress test. I was only on the treadmill for maybe 4 1/3 minutes before I experienced SOB and chest pains. They repeated the ECG and I was told it was abnormal and to discuss my medications with my psychiatrist and that I had nothing to worry about. When I see abnormal ECG, EKG and am taking nitro tablets with a family history of heart disease (father COPD, CHF and angioplasty; grandfather died of a heart attack), I have a tendency not to believe the doctor. I have not even been contacted by my physician for a follow-up visit. Should I be concerned. Cancer also runs in my family; my father died of colon, liver CA and I am breast cancer survivor. I d appreciate your comments. Should I seek another opinion? Thanks, Mary Kopco YYYY@YYYY I am a 61 y.o. white female, 137 lbs w/ hx of cancer (bilateral mastectomy and hysterectomy for CA of uterus), osteoporosis and osteoarthritis, high cholesterol (328), allergic to any statin drugs, being treated with Zetia 10 mg 1 x/day. Presently taking nitro tabs for chest pain, oxybutityn for overactive bladder, clonazepam 1mg 3x/day for anxiety and depression. I look forward to your response. Thank you.
I am a 24 year old male. I have PVC s and PAC s. I am extremely active and in great physical condition, I spend 1.5 hours, 5 days a week working out. I am 225 lbs, 8% body fat, and 6ft tall. I take no supplements. Recently I have been having some worrisome palpitations. Usually in the early morning my heart will either beat extremely fast (180-250bpm) for a few seconds accompanied with near syncope and SOB or it will beat erratically. I had an extended episode (30 seconds) of appx 200-250 bpm brought on by a sprinting session about 2 months ago. That is when these strange rhythms began. Normally I feel my PVC s, so I am very aware of my heart beat. My heart feels strange like it is tired latley. What could this be? I am worried about VTach, but as I do not have insurance I am wary of going to the cardiologist. What should I do? Thank You
i am 38 years old, 6'5" and 330 pounds. I've been having severe heart palpitations with shortness of breath that seems to rise up my body. First i get a warm feeling in my left ear, then i get very dizzy and start seeing white spots, then it feels like i'm losing oxygen to my head and i start to blackout. it usually goes away after i close my eyes and sit still. i have been to cardiologists who told me that i have high blood pressure and could lose weight, but my angiogram, etc. all prove normal. i am taking a beta blocker (cardovilol or something) plust a high blood pressure medication.
Hi. I am a male. As long as I can remember, i have experienced a sharp, burning chest pain that occurs randomly. It does not radiate and usually only lasts a few seconds. It is not brought on by exercise. I also occasionally experience palpitations. Sometimes, it feels like my heart stops and skips a beat and then continues. I also can feel my heartbeat sometimes and it beats fast and hard. My usual resting heart rate is about 103. My BP is about 128/76. I have panic attacks also. Occasionally, I feel lightheaded which usually only lasts for a few minutes and is followed by extreme anxiety. I sometimes get nauseous and have irregular bowel habits. Sometimes I am constipated and other times I have diarrhea. I have seen my doctor and had blood work and a EKG done. Palpitations did show up on the EKG but my doctor says they are not serious. Some people have suggested I have acid reflux. I seem to have some symptoms of MVP but I was never diagnosed with it.
I have high blood pressure(165/110) and was put on Lisinoprin 3 weeks ago and it has come down about 30 points...however i have head aches and have shortness of breath . I wake up at night and feel like i'm not getting enough oxygen . I weigh 260...
I was diagnosed with attrial flutters ( arrhythmia ) and the cardiologist did a cardio version and a subsequent EKG showed the condition was corrected. The doctor has me on Xarelto and a beta blocker . I feel fine and I am wondering if I can drink...
My husband is 80 years old and has been diagnosed with congenial heart dease. His heart is only pumping half the speed of a normal heart beat. And now his lungs are filling with fluid. He also has Alzheimer's.
