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.
the other day when driving i skidded out on the ice and almost slammed into a truck coming the opposite direction. i was fine but my heart began beating slowly and pounding with the fear rather than faster. it took almost a minute for it to go back to normal and i was terrified. is this normal? or is this something i should be worried about. i have heard about something called long QT syndrome, but do not know if this is a normal human reaction under intense sudden startled such as that, thanks
27 yr old male, former smoker. no other heart problems
I am a 23 year old female, studying medicine. For past 8 months, i have been having some episodes of heart 'dysfunctions' that now have turned constant. I need help in knowing what is the condition. It started last may when one day i started feeling so weak that i just could not get up and was having a splitting headache, when i measured my BP was 90/55mmHg ( before it was always 120/80mmHg). I was having palpitations, bradycardia at times, tachycardia at times, extreme weakness, sweating ( especially on scalp) after sleeping after headache. I was also having light sleep. Slowly, these episodes became constant. Now I am feeling weak all times, light headed if sitting or standing for long, headache (thumping with constant heaviness), inability to sleep, tightness in chest, chest pain sometimes, tachycardia at any normal activity (walking, doing some tidy up), BP is still low. I also get dry cough on breathing sometimes. So i got a holter done for 24 hours, got following: - sinus tachycardia( 110- 120) almost all day with some normal rate in between, my heart rate dropped to 50 in middle of night ( reason causing me to wake up from sleep and not to sleep again) and it remained like that for 3 hours - average pulse -81 - my heart rate jumped to 179 per min when i climbed stairs ( 9 floors, easily climbed by others), breathing became laboured, headache with blacking out sensations ( i did not faint though) - I have some abnormalities in lead I, II and III ( looks like left axis deviation as lead I is showing highest peaks and is moving away from III ) even the avL and avF looks weird, QTc>450ms is 47%, no ST deviation, no T wave abnormalities I also have tachypnea (26-28 per min) and accentuation of Pulmonary part of second heart sound. I also have slight edema on my feet ( bluish tinge) I also did a blood work up, I do not have thyroid problems or anemia I need some advice on what i might be having, so as to proceed further on treatment.
About four years ago, I was diagnosed with ventricular tachicardia. I was given a catheter ablation to treat it, and it corrected an irregular heart beat that I've had since I can remember, but I still experience the rapid heart beats every now and again when Im out running or doing some other strenuous activity. Another thing that I've had since I can remember is excessive sweating, and I mean very excessive. What it takes for a normal person to sweat, it would take A LOT LESS for me. My question is, is the excessive sweating linked to the tachycardia? Of course, tachycardia causes the fast heart beat which in turn causes the sweating, but even when Im not experiencing the rapid irregular heart beats, I still manage to completely soak a t shirt when the guy next to me whose done the same amount of work is completely dry, aside from a few sweat beads on the forehead.
my blood pressure is 138 over 82 and my heart rate is 56 - my heart rate hardly ever reaches 60 beats when resting and bp is normally 116 over 72 - should i be worried about slow heart rate i am not at all fit athletic - i am a 55 year old woman with a history of sarcoidosis
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.
