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 more
Slow heart rate, also called bradycardia, is defined as a resting heart rate (pulse) less than 60 beats per minute. Having a heart rate less than 60 is not necessarily abnormal. In fact, people in good cardiovascular shape have a low heart rate. People with certain heart conditions may take medications which lower the heart rate as one of ...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 more
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 more
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 more
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
Is sharp, occasional back pain a concern with a person with tachycardia and bradycardia? Diagnosed with IST but now presenting with slow HR as well.
Brady/tachy: There is a common syndrome called brady/tachy syndrome also called sick sinus syndrome which has both tachy and bradycardia as parts of the problem. ...Read more
I go from tachycardia of 120-160 to bradycardia 49bpm. What could cause these huge alterations in heart rate? Always at rest.
Multiplr issies: Cardiac irregulariities must be seen and checked with EKGs, Holter monitoring and blood tests- multiple contributing issues- address with your cardiologist. ...Read more
I have a pacemaker for bradycardia but over the past two months my pacemaker has been reading a high rate of atrial tachycardia should I be worried?
Monitor: To know what your pacemaker is recording, you must be seeing your doctor to have the device interrogated. You should ask your doctor the meaning of the rhythms that the device is recording and whether anything else is needed. ...Read more
Can having autonomic dysfunction and taking 20 mg Paxil (paroxetine) be dangerous? Have problems with bradycardia and tachycardia. Got effect of Paxil (paroxetine) after 5 min!
The effects on blood pressure have been reported to be inconsistent.
Cardiovascular side effects have frequently included palpitation (2% to 3%), vasodilation (2% to 4%), hypertension (2%), and tachycardia (including torsade de pointes). Bradycardia, hematoma, hypotension, postural hypotension, syncope, angioedema, angina pectoris, nodal arrhythmia, atrial fibrillation, bundle branch block, . ...Read more
14 day loop results states tachycardia up to 140, bradycardia 42 bpm, ventricular ectopic complexes, supra ventricular ectopic complexes and an atrial couplet. Should I be worried?
Arrhythmias: You should be talking to your doctor about the situation to get more information. The rhythms alone don't necessarily imply something 'bad'. On the other hand if you were entirely normal they wouldn't be there. The rest of your condition is what tells you whether you should be worried. Your doctor is best positioned to answer that question. ...Read more
In order to have an arrhythmia, do you have to have either tachycardia or bradycardia? Or can you have an arrhythmia and have a normal heart rate?
Yes: You can have irregular heart beats with normal rate in a minute ...Read more
I had a period of time with tachycardia & high BP, then I had med for2 mnths&then discontinue, now I have bradycardia& occasionally high BP, arrhythmia?
Halter monitor results say sinus bradycardia to sinus tachycardia with sinus arrhythmia. Should I be concerned?
Prescribed digitek (digoxin) for tachycardia from pots syndro, also have bradycardia with RHR 40s at times. Scared to take it. Lowers heart rate how much? Safe?
Want to know what is the cause of alteration between bradycardia & tachycardia+bounding heart, I had sleep apnea before&moderate pulmonary hypertension?
See below: That would be really difficult to answer on here. You need an evaluation by your cardiologist. ...Read more
Please, what is the cause of alteration between bradycardia & tachycardia+bounding heart, +tired, had sleep apnea before&moderate pulmonary hypertension?
Short PR interval no delta wave, short paroxysmal aFib, IRBBB, different types of extrasystoles and tachycardias plus night bradycardia. Diagnosis?
Lown-Ganong-Levine: Same family as WPW with concern for accessory pathway connecting atria directly to ventricles. BUT unlike WPW, LGL is more benign, and the AV node still possesses decremental conduction. ...Read more
Mechanisms vary: Bradycardia simply means slow heart beat. Sinus bradycardia refers to a specific cause for the slow heart beat which is sluggishness of the natural pacemaker cells of the heart (referred to as sinus node). This could be normal in physically fit people or abnormal especially if associated with symptoms of fatigue, shortness of breath or passing out spells. ...Read more
Not usually: Only if accompanied by symptoms like enervation, dizziness, shortness of breath. If naturally occurring (no heart rhythm disturbance or medication adverse effect) and no symptoms, probably would simply observe. Otherwise, underlying conditions need to be sought and treated accordingly. Some may require a pacemaker if symptomatic and not responsive to conservative therapy. ...Read more
