I recently have an ECG done as I would occassionally feel a bit of a flutter contained by my chest and I received the following results.
Sinus Rhythm
Marked PR Prolongation (0.44 sec)
HR 66/min
***Intervals*
RR 906 ms
P ms (there was no digit there)
PQ 378 ms
QRS 86 ms
QT 356 ms
QTc 374 ms
*Axis*
P -999 degree
QRS 65 point
T 40 degree
From what I've read, my P-R interval is double of what is considered middle-of-the-road, however, I was wondering if someone can please provide me some overall information based on those results.
Answers: You own first degree A-V block because you own a prolonged pr interval. This just ability that it takes longer for the signal to grasp from your atria to your ventricles. Nothing to worry just about. I don't know what is causing the fluttering within your chest. You should have a holter monitor which is usually kept on for 24 hours so if you hold the fluttering the machine will detect it................
Although I am not a cardiologist (I am a M.D. though), from what you report it does nouns like a possible luggage of first degree heart block. (But its OKAY!, I hold it too! (smile))
On an electrocardiogram (ECG), the PR interval (which is defined as the time from the initial deflection of the P wave to the start of the QRS complex) should be between 120 and 200 msec. First-degree heart block, or first-degree atrioventricular (AV) block, is defined as prolongation
of the PR interval on the ECG to more than 200 msec. (Your PR interval by the mode is 440 milliseconds).
What is the PR interval?
The PR interval is a part of the electrocardiogram that represents the electrical depolarization thrash traveling through the heart's upper chambers (the atria) and after a little time deferment (to allow the contracting atria to squirt the blood down into the lower chambers (the ventricles). The electrical thrash starts out fast (kind of approaching running on the
beach) then drags for a moment (like running knee philosophical in the surf); this slow-down is adjectives of the delay the atria inevitability to move the blood to the ventricles. Then the wave speeds up again while moving through the big pumping chamber (ventricles).
What is the significance of an elongated PR interval?
Although an elongated PR interval CAN be indicative of heart disease, if you are young and athletic, an elongated PR interval is a COMMON finding (like I said already, I own it). The PR interval gets lengthened next to high vagal tone. Vagal
tone can be explained as follows: The heart have electrical inputs from both sides of the autonomic nervous system (ANS). The ANS is a slice of the nervous system to be exact automatic and deals next to the balance between "argument or flight" versus relaxed, vegetative body responses. There is a
gas-pedal, accelerating (sympathetic) side (think adrenalin) and in that is a vagal side that is dominant during our relaxed moments. Consider that if our heart raced all light of day, we would just plain wear out; so near needs to be a be a foil for between the two sides of the system.
How do you get an elongated PR interval (so-called "first level heart block" or "AV block")?
Heart block can be congenital (you are born with it) or acquire. Acquired heart block can be due to a previous inflammation of the heart (myocarditis), which can lay down scar tissue surrounded by the electrical conduction pathways of the heart; medication (many will slow the electrical conduction within the heart) or athleticism. Athletes (does this apply to you?) can develop increased vagal tone, slower heart rates overall and a 1st point heart block.
In and of itself, first-degree AV block is a benign condition, with no associated increase contained by morbidity or mortality.
The following are the most common cause of first-degree AV block:
o Intrinsic AV nodal disease
o Enhanced vagal tone (for example, "athletic heart")
o Acute MI, particularly acute inferior wall MI
o Myocarditis
o Electrolyte disturbances
o Drugs (especially those drugs that increase the refractory time of the AV node, thereby slowing conduction)
Recommendation:
I would recommend have a cardiologist review your EKG. The only explanation I say to be precise that you ALSO mentioned a chest "flutter." A flutter can be due to different things, such as a premature ventricular contraction (we can all procure those with too much coffee), but possibly that flutter represents what is known as an "escape rhythm." If here are no underlying
pathophysiological reasons that would prevent athletics and a ordinary lifestyle, I would at that point then quality completely reassured. But you SHOULD enjoy the EKG evaluated for any underlying significance. Any lab test (this occupancy would include EKGs, X-rays) interpreted within a vacuum is solitary of limited worth. You stipulation a clinical exam to put the
lab finding within the proper context.
I own lots of small scar on my arms and legs from when i be little, how to i receive rid of them completely.?
Terrified of MRI?
Do I hold a kidney infection?
