EKG has recently started showing biphasic T waves, it didn't before. Had one yesterday, showed Rightward Axis Borderline EKG. What would cause this?

EKG has recently started showing biphasic T waves, it didn't before. Had one yesterday, showed Rightward Axis Borderline EKG. What would cause this?

Several causes: These may be a normal variants to conditions that might need further evaluation. Being able to look at the EKG is essential to making a diagnosis. Please consider having a virtual consult so you might discuss this further.
Best of luck! ...Read more

P waves usually biphasic in V1 but become only upright with exercise? T waves in leads V2-3 also change with every ekg.

P waves usually biphasic in V1 but become only upright with exercise? T waves in leads V2-3 also change with every ekg.

Lead placement can: Make a significant difference in the morphology of the EKG waveforms just as body position can. Sitting or lying while resting makes a significant difference from standing while exercising. None of what you describe sounds worrisome at all. ...Read more

What is usual p wave orientation in V1 and V2? What does inverted p wave V1 and biphasic in V2 mean? Is it common? Heart rate 95. athlete.

What is usual p wave orientation in V1 and V2? What does inverted p wave V1 and biphasic in V2 mean? Is it common? Heart rate 95. athlete.

The P waves: (Atrial depolarization/repolarization) in the V (anterior chest) waves are PLACEMENT (of the electrodes) DEPENDENT!! the "inversion" or "biphasic" descriptions HAVE NO CLINICAL SIGNIFICANCE!
Hope this is helpfu!

Is an upright P wave V1 and inverted P wave aVL with tachycardia indicative of ectopic rhythm? Other ekg shows biphasic P wave V1, upright P wave aVL

Is an upright P wave V1 and inverted P wave aVL with tachycardia indicative of ectopic rhythm? Other ekg shows biphasic P wave V1, upright P wave aVL

If the tachycardia: Is occurring at rest with changes in the P wave morphology then it might be an ectopic atrial tachycardia. If it is occurring during exercise it is not diagnostic and may still be a normal sinus mechanism. ...Read more

What does it mean to have biphasic scoliosis?

What does it mean to have biphasic scoliosis?

This is not a formal: This term "biphasic" is not a normal term when used to describe a scoliosis. There are several different types of scoliosis classified on their causes (idiopathic, congenital, neuromuscular) & then we describe scoliosis based on its location and appearance on radiographs or x-ray (thoracic, thorcolumbar, lumbar, cervical, - single curve, double curve, major curve, minor curve, kyphoscoliosis, etc. ...Read more

Is biphasic sleeping safe?

Is biphasic sleeping safe?

I think so: Many societies have traditions of prolonged (compared to the us) midday napping. In certain mediterranean groups known for longevity this activity is the rule not the exception. My empirical observations have been that sleep patterns are very individual. A measure of health is absence of fatigue and depression. The happiest people sleep whenever and however they can, and whenever they feel a need. ...Read more

How can I break my biphasic sleep pattern?

How can I break my biphasic sleep pattern?

Sleep hygiene: Probably the best way is to apply sleep hygiene. Choose the one period of sleep you are want and treat the other as a 'nap' which you would eliminate. Allow yourself to extend the length of the single sleep period every few days until you reach a number of hours that provides a restful sleep. Do not nap, keep sleep structured with same time to sleep and eventually same time to wake. ...Read more

What are the effects of alcohol on RBC? Does alcohols have biphasic effects on RBC deformability?

What are the effects of alcohol on RBC? Does alcohols have biphasic effects on RBC deformability?

Explanation below: Alcohol is associated with a macrocytic (with large RBCs) anemia and can also, by irritating the stomach, cause blood loss and iron deficiency. RBC deformability is more likely to be related to abnormal hemoglobin content (sickle cell anemia is the most well-known, but there are others as well). ...Read more

I was wondering is biphasic isophane insulin, insugen 30/70 chemically the same as mixtard 30hm penfill insulin?

I was wondering is biphasic isophane insulin, insugen 30/70 chemically the same as mixtard 30hm penfill insulin?

Insulin mixtures: These insulins do not appear to be available in the US. 70/30 mixes are usually a mixture of NPH and regular. NPH is intermediate in duration (peaks about 10 hr, lasts about 24 hr) and regular peaks about 3-4 hr, lasts about 8. It may say on the bottle or package insert what kind of insulin. Look for the words "NPH" and or "regular". ...Read more

TTC for 9 months, irregular cycles (29-50 days), consistent biphasic BBT charts, early 20's... What could be wrong?

TTC for 9 months, irregular cycles (29-50 days), consistent biphasic BBT charts, early 20's... What could be wrong?

Likely nothing: Infertility is defined as unprotected intercourse without conception for one year. This is based on about 85% of normal couples conceive in that time. If 23 years is your correct age, you could certainly try another 4 months; or most fertility doctors would be glad to help you anytime. ...Read more

Can biphasic sleep effect growth? I am a 17 years old boy and I want to sleep at about 10pm to 2 am then 4 am to 7am. Would that stunt my growth?

Can biphasic sleep effect growth? I am a 17 years old boy and I want to sleep at about 10pm to 2 am then 4 am to 7am. Would that stunt my growth?

Possibly: There are several phases of sleep and one of the most important levels for maximum rest and renovation is delta phase. This is the deepest level of sleep in which hgh (human growth hormone) is released and in adults provides one of the most potented hormones that naturally helps prevent tissue and organ breakdown. In growing individuals, adequate hgh levels will insure proper growth. ...Read more

Is biphasic sleep a stable sleep schedule or can it harm me? I can't really find sources proving it wrong or bad so why not use it?

Is biphasic sleep a stable sleep schedule or can it harm me? I can't really find sources proving it wrong or bad so why not use it?

See below: Polyphasic (incl. Biphasic) sleep can result in disrupted schedules, usually less total sleeping time, ; of course disrupted sleep. Moreover, our rapid eye movement (rem) sleep ("dream sleep") cycles approx. Every 90 min., ; so you may lose that pattern. Rem sleep is important ; is linked to consolidation of memory. Try not to substitute "power naps" for good quality sleep. Hope that helps! ...Read more

What is biphasic pulse? Does this mean if you feel double beat in your carotid artery you have HCM? How is it detected? Thanks

What is biphasic pulse? Does this mean if you feel double beat in your carotid artery you have HCM? How is it detected? Thanks

Two peaks/heart beat: Instead of just one, aka pulsus bisferiens: https://en. Wikipedia. Org/wiki/Pulsus_bisferiens. HCM, hypertrophic cardiomyopathy, is only one possible basis via subaortic stenosis. Detection is normally by palpation (feel) which requires practice & comparison with a normal pulse in a similar location to appreciate. An easily felt double-pulse in carotid is more likely due to a premature beat. ...Read more

I'm 48, biphasic bbt, negative OPK with peak at temp rise. Can my TSH of 3.1 be cause of no menstruation for 1.5 yrs?

I'm 48, biphasic bbt, negative OPK with peak at temp rise. Can my TSH of 3.1 be cause of no menstruation for 1.5 yrs?

Not likely: Your TSH is normal so this is not likely to contribute. At age 48 ovulation is going to be inconsistent. If you have not had a menstrual cycle in 1.5 years then menopause is the most likely explanation. An Obgyn can do an evaluation for you to determine what is going on ...Read more

Doc thought I had a dvt in my leg post op. ER did ultrasound and found biphasic flow in lower extremity and said pvd. I am 27yo. Is this likely?

Doc thought I had a dvt in my leg post op. ER did ultrasound and found biphasic flow in lower extremity and said pvd. I am 27yo. Is this likely?

Usually a: Venous doppler ultrasound is performed to evaluate for DVT (maybe you had it done as well), but you are describing findings of an arterial doppler. Biphasic flow is abnormal and suggests PVD, as you describe. It would be every unusual for a 27 yo to have significant atherosclerotic changes unless you are diabetic or have another predisposing disorder, so you need to talk to your doc about results ...Read more
