What Are Differences Between Bradycardia And Tachycardia
Fast versus slow: Bradycardia & tachycardia just mean slow & fast heart rate, respectively. Each does not necessarily indicate a problem and can be normal & appropriate. For example, sinus tachycardia is a normal response to exercise or fear. If your hr does not increase with exercise, that can be a major problem. Also, bradycardia during rest (e.g., during sleep) can be normal too, especially in an athlete. ...Read moreSee 2 more doctor answers
Slow heart rate is a symptom in which a person's heart rate (the number of heart contractions per minute) is less than normal for the average person of the same size, doing the same activities. For adults, slow heart rate usually means a rate below 50-60 beats per ...Read more
It depends: In some cases, these can be normal states (an athletic person with bradycardia) or due to another condition (tachycardia with overactive thyroid, too much alcohol, or anemia) that needs to be treated. Otherwise, either can cause dizziness or fainting, fatigue, and inadequate blood flow (which can cause heart damage or even a stroke). The safest approach is treatment. ...Read moreSee 2 more doctor answers
Depends: Asymptomatic bradycardia is not associated with any risk usually, typically athletes have profound bradycardias and it is a sign of their fitness. Tachycardias when left untreated for an extended period of time (dependent on the rate and the age of the person) however can lead to a weak heart. This condition is usually reversible and is called tachycardia-induced cardiomyopathy. ...Read moreSee 1 more doctor answer
More data needed...: I would be interested to know what the actual heart rates were when you stood. It would also be important to know if you had a blood pressure change when you stood, and if you are becoming dizzy with standing. Possible explanations for this scenario might be dehydration, medication that causes low blood pressure, or dysautonomia (e.g., pots). Recommend discussing this with your physician! ...Read moreSee 1 more doctor answer
Orthostatic: Doctors & nurses check vital signs (blood pressure & heart rate) in lying, sitting, & standing (orthostatic) positions to assess if whether a patient's blood volume is decreased, eg. from dehydration or from bleeding. Other factors can also influence the orthostatic response, including normal and abnormal ("POTS") reflexes. For help with your own situation, get a cardiology consult on HealthTap. ...Read more
For 2.5 years have suffered with tachycardia daily/nightly. Past two weeks have had bradycardia (as low as 38bpm). Strange? What can cause this?
Brady/tachy: Details including ECG matter in differentiating several potential causes,you are strongly urged to further evaluation ...Read more
Electrolytes: Hyperkalemia can caus several ECG abnormalities. First one may see "peaked t waves". Ventricular ectopic beats (pvc's) as well as tachycardia may develop. If untreated the rate can slow and a "sine wave pattern" which is a wide slow wave form that is a pre-terminal rhythm. Hyper kalmia is a medical emergency that needs to be treated rapidly. ...Read more
Tachy/brady: Alternating resting tachycardia/bradycardia is not normal. You should have your doctor investigate to see what could be going on. ...Read more
Depends: Depends on how fast or how slow, the cause for the abnormal rate and whether or not it is causing any symptoms. Both abnormally slow and fast heart beats can cause congestive heart failure and syncope (fainting). Persistent fast heart beats can cause weakness of heart muscle referred to as tachycardia induced cardiomyopathy. ...Read more
