S P Cardiac Arrest
Maintains heart rate: The normal heart rate is roughly between 60 to 100 beats per minute. For some, there is difficulty in maintaining adequate heart rates for a variety of reasons. In these patients especially the symptomatic ones, a cardiac pacemaker may have to be implanted. ...Read moreSee 1 more doctor answer
Arrhythmia: Scd typically refers to a sudden loss of effective contraction of the heart muscle and implies a life-threatening arrhythmia. Usually this is VT or vf. It occurs primarily in patients with a damaged heart (cardiomyopathy, postmi) where there is scar tissue that alters normal electrical conduction. It can also occur in patients w nl hearts (brugada syndrome, arvd, long qt) which are rare. ...Read more
Overlap sometimes: Asystole is no beat at all. Flaccid still heart. Cardiac arrest : includes that and ventricular fibrillation or tachycardia, which are ineffective rhythyms and no pulse. These can happen with a heart attack which is death of some portion of the heart muscle. ...Read moreSee 1 more doctor answer
No: Premature ventric contractions (pvcs) and rapid hr (tachycardias) are arrhythmias (abnormal rhythms); can occur with or without intrinsic heart disease. Heart dis. Usually from blood vessel disease. Main cause is atherosclerotic buildup of plaque inside others: infection, xs iron, xs muscle, etc. Abn rhythms can be from xs caffeine, tobacco, alcohol, meds, cocaine, dehydration, fever. ...Read moreSee 1 more doctor answer
Needs rapid evaluation: Although chronic hypertension is among the most common causes of nonischemic cardiomyopathy, there appears to be no hypertensive history in this case. With an ejection fraction of 20%, sudden life-threatening arrhythmia is a significant risk. An implantable defibrillator must be considered urgently. A Zoll Vest could be considered if there is any delay in implanting a defibrillator. In addition, consideration should be given to a myocardial biopsy to search for an infiltrative cardiomyopathy. Diuretic, beta blocker and vasodilator therapy might be limited by a low blood pressure. If there is a wide QRS, resynchronization with a biventricular pacemaker might help restore ventricular function. The prognosis (and treatment) will be dependent upon the underlying cause of the cardiomyopathy. ...Read moreSee 9 more doctor answers
Ct angio score of zero, stress echo normal and event monitor only ectopic beats...does this rule out CAD? Dad heart attack at 50 still alive. Help?
Predominantly sinus rhythm, with evidence of 2:1AV heart block (type II). 3rd degree block reported, now thought to be 2 beat P wave asystole. worry?
Short PR interval & early repolorasation pattern on ECG. Multiple runs of NSVT. Cardiac MRI ruled out structural heart disease. What can this be?
See below ...: cardiac arrest: pumping or rhythm abnormality so severe that the flow of blood thought the heart is super low or zero - incompatible with life unless successfully treated. heaty attack - region of heart muscle get less oxygen than it needs so the muscle dies. heart failure - heart is unable to adequately deliver oxygen to the body, or requires an unhealthy amount of filling pressure to do so. ...Read more
At the er for chest pain hospital monitor says couplet pvcs amd sv rhythm. What does sv rhythm mean? and are couplet pvcs dangerous?
Not necessarily: SV="supraventricular rhythm" which is normal. PVCs are "extra beats" that sometimes lead to the feeling of a thump or irregular heart beat. By themselves, extra PVCs or couplets of PVCs are not dangerous. Some people get them when they drink caffeine or smoke cigarettes. They aren't an indicator of a heart attack, but if they happen during a heart attack, they can be a sign of impending problem ...Read more
Heart rate 40-50 BPM results from stress test, echocardiogram, ekg, 24hr holter monitor all "normal" could my slow heart b due to genetics/other factors?
Ecg , cardiac echo, heart enzyme , chest ct, cardiac angio ct, all ok.Still resting heart pulse 53-62.Increase when move.Exclude cardiac issue?
Depends on: Why you had the cardiac arrest. If due to coronary artery disease, you should avoid simple carbs and get plenty of aerobic exercise. Look at lowglycemicindex.Com. Also avoid caffeine and stimulants. If another cause, like hocm, valve disease, arrhythmogenic right ventricular dysplasia or some other cause, look to treat the underlying cause first. ...Read moreSee 1 more doctor answer
Stopped heart: Cardiac arrest occurs when the heart stops pumping blood forward . The stoppage is usually due to to a change in the heart's electrical rhythm that prevents the muscle cells from squeezing in an organized fashion. Cardiac arrest can also occur with a normal heart rhythm, if the heart is too weak to pump blood or too empty to have blood to pump. In any case, immediate resuscitation is needed. ...Read moreSee 1 more doctor answer
Heart stops: Cardiac arrest is when the heart stops beating effectively. The heart actually ceases to beat or the heart has other electrical rhythm disturbances in which the heat no longer can work as a pump. Because of the lack of blood flow to the brain, patients become comatose, and stop breathing. Unless the condition is reversed quickly, death follows. CPR can provide some protection until help arrives. ...Read moreSee 1 more doctor answer
Not common: Unfortunately, uncommon. Hard to say exactly, & depends somewhat on what kind of cardiac arrest, what other problems the person has, how long before care, etc. Generally though, for out-of-hospital arrests, less than 20% survive long enough to be discharged from the hospital. Also concerning is how often cardiac arrest is the 1st sign of underlying CAD (plaque in vessels). See a proactive doctor! ...Read moreSee 1 more doctor answer
Sort of: Is a calf a cow? If you are making veal parm? Cardiac arrest is the loss of pumping ability of the heart. That is measured as cardiac output (units l/min). In cardiac arrest it is 0. Asystole is usually used to refer to the lack of electrical activity in the heart. If the electrical system could be measured, it would be measured in amps (current or electrons /sec). In asystole that is 0. ...Read moreSee 1 more doctor answer
Yes......: During a cardiac arrest, the heart stops contracting so that there is no blood being circulated to the organs. Cardiopulmonary resuscitation is performed to restore contractility. If successful, the person survives. The longer it takes to "re-start" the heart, the more likely there will be residual effects, like brain injury due to decreased oxygen to the brain during the arrest. ...Read more
Depends: If you go into cardiac arrest, after about 10 seconds you will pass out, lights out. If the cardiac contraction and rythm do not resume spontaneously you will be brain dead within 5 minutes. So after 10 seconds if you do not get rescued, you will never know if you went into cardiac arrest. ...Read more
Many reasons...: Sometimes there is an unknown congenital heart defect which goes undiagnosed and then results in a sudden cardiac arrest during exercise. Sometimes, an object, like a baseball, hits the chest at just the right time during the cardiac cycle resulting in cardiac arrest. So, there are many reasons for this unfortunate event to occur. ...Read moreSee 2 more doctor answers
