Hyperkalemia leads to bradycardia or tachycardia?

Hyperkalemia leads to bradycardia or tachycardia?

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

Hyperkalemia (Definition)

Hyperkalemia in an elevated potassium level in the blood. It can be mild to severe. The most common causes are kidney disease, Addison's disease, dehydration, and multiple drug therapies. It can occur in crush injuries and rhabdomyolysis (rapid breakdown of muscle) or hemolysis (breakdown of blood cells). Severe hyperkalemia can be fatal and cause the heart to stop beating or become very slow. It is usually treated by resin exchange agents (Kayexalate or others) or dialysis and fluids. Sometimes glucose, Insulin and sodium bicarbonate can be utilized as ...Read more

Are pvcs, bradycardia, and low BP related?

Are pvcs, bradycardia, and low BP related?

Usually not: But it's possible. Extreme bradycardia (hr <40) can precipitate pvcs and, that aside, extreme bradycardia can cause low bp. You should be fully evaluated. ...Read more

How does atrial and ventricular tachycardia affect blood pressure and cardiac output?

How does atrial and ventricular tachycardia affect blood pressure and cardiac output?

Different arrythmias: They come from different chamber ( upper vs lower) . Changes in BP and cardiac output depend on cardiac function , heart rate and and timing. Atrial fibrilation may decrease cardiac output about 15%. In ventricular tachycardia, BP and co will decrease more if it is long enough to become unstable. ...Read more

Can low potassium cause bradycardia?

Can low potassium cause bradycardia?

No: A low potassium is usually associated with extra heart beats or abnormal tachycardia. A high potassium, on the other hand, can cause heart block, bradycardia, even systole. ...Read more

Heart palpitations and dizziness. Ekg showed- shortened pr interval, and high lateral/lateral repolorization disturbance?

Heart palpitations and dizziness. Ekg showed- shortened pr interval, and high lateral/lateral repolorization disturbance?

R/O LGL Syndrome: The association of tachycardia and a short pr interval on an ekg may indicate an abnormal electrical pathway in the heart that can cause frequent palpitations and a sustained rapid heart rate. There are two syndromes called wolf-parkinson-white(wpw) and lown-ganong- levine(lgl) that are associated with short pr and tachycardia . Medication or ablation can prevent the palpitations and tachycardia. ...Read more

Why can hypotension occur with relative bradycardia in ai?

Why can hypotension occur with relative bradycardia in ai?

Physiology: Aortic insufficiency (ai) means that the aortic valve leaks during diastole, which is the relaxation phase of the cardiac cycle. Relative bradycardia means there is a slowing of heart rate which also means a prolongation of diastole. A prolonged diastole does mean more ai which results in lower blood pressure (i.e. Hypotension). ...Read more

What are the issues with cardio arrhythmia and congestive heart failure?

What are the issues with cardio arrhythmia and congestive heart failure?

Many rhythms: Patients with congestive heart failure are at risk for several different abnormal heart rhythms, including life threatening and more benign rhythms that can affect quality of life. The most common arrhythmia is called atrial fibrillation - it is treated with blood thinners, medications to control the rhythm, and sometimes procedures. An implanted defibrillator (icd) can protect from sudden death. ...Read more

Are pvcs and tachycardia considered heart disease?

Are pvcs and tachycardia considered heart disease?

Pvcs and tachycardia: Well your questions is really two parts.Firstly tachycardia, which really means rapid heartbeat more then 120 beats per minutes and has many causes which may be from heart disease or other conditions like hyperactive thyroid and certain medications.But pvcs are abnormal beats and are always due to problems in heart, and you need to see a cardiologist, it can be serious. ...Read more

Why do you take betapace, xocor, digoxin, and Coumadin (warfarin) with atrial fibrillation and sinus tachycardia?

Why do you take betapace, xocor, digoxin, and Coumadin (warfarin) with atrial fibrillation and sinus tachycardia?

Prevent stroke: Actually atrial fibrillation and sinus tachycardia are two completely different heart rhythms. None of these drugs would be of any use for sinus tachycardia. In atrial fibrillation, Betapace may restore a normal rhythm. Digoxin can help keep the heart rate down. Coumadin (warfarin) reduces the risk of stroke. Zocor also reduces stroke risk in some patients, but this is unrelated to the atrial fib. ...Read more

Slow Heart Rate (Definition)

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
