What Is The Most Common Underlying Cause Of Sudden Cardiac Death In Children
Genetic abnormality: Mutiple genetic defects may unfortunately lead to sudden death. The most common include long qt syndrome, hypertrophic cardiomyopathy, and brugada syndrome. Others are being identified all the time. Often there is a family history of premature sudden death. Some people have prior palpitations, dizziness, or syncope before the episode of sudden death. Genetic screening blood tests are available. ...Read moreSee 1 more doctor answer
Respiratory failure: Benzodiazepines are central nervous system depressants ('downers') so when mixed with alcohol or taken in excess they cause respiratory failure (stop breathing). Several famous people may have died this way: marilyn monroe, elvis and even heath ledger had 3 benzodiazepines in his system. However, respiratory failure leads to cardiac failure. ...Read moreSee 1 more doctor answer
My prescription BP med does a good job getting my systolic perfect but pushes diastolic too low. I hear this is bad and can cause sudden cardiac death?
Systolic BP: Generally, we follow the systolic BP in the outpatient setting -- because the diastolic BP is hardly accurate using the portable BP machine -- then again, if you don't feel well, regardless of the numbers, you need to seek medical attention ok. ...Read more
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
Timing: If the person has signs of obvious death (rigor / livor / rubor / calor -mortis =dependent blood pooling, rigid muscles, cool/cold to touch, etc.), then most jurisdictions allow declaration of death, police notification & they stand by for medical examiner. If recent collapse or can't tell (scd), then start cpr, secure the airway, start iv, give meds/shocks and transport to er. ...Read more
Not always: Sudden cadiac death may be associated with asymtomait congenitalt abnormalities such as arrhythmogenic right ventricular cardiomyopathy, long qt syndromes, brugada syndrome , wpwsyndrome, hypertrophic cardiomyopathy also with such condition as cardac sarcoid.This is compaired to symptomatic condition as ashd, end stage low ejeection cardiiomyopathies. ...Read more
Sudden cardiac death: SCD means a cardiac arrest which occurs shortly (usually defined as <1 hour) after the first symptom. Aborted SCD would mean that the cardiac arrest was treated, e.g. by defibrillation. Causes of SCD include acute myocardial infarction, ventricular tachycardia/fibrillation, and heart failure. ...Read more
Sudden cardiac death: Read the info in the link here. And if you aren't in one of the high risk groups there, realize that your chances of SCD are extremely low. If this doesn't help you might need to get some psychologic therapeutic aid to help redirect your attention more productively. http://www.webmd.com/heart-disease/guide/sudden-cardiac-death?page=1 ...Read moreSee 1 more doctor answer
Fear: For my patients with that fear who have no evidence of heart abnormality or family history of sudden death, i spend time reassuring them and explaining their low probability of sudden death. With the occasional patient we have done testing such as ecg, echo and treadmill to document low risk for sudden death to help reassure the patient. Sometimes psychiatric help is needed. ...Read more
I was just found out I have early repolarization. Should I be worried about sudden cardiac death?
I feel like coming down with cold, will I get myocarditis as complication and have sudden cardiac death ? What should I do?
Cardiomyopathy: Although there are infectious agents which can cause cardiomyopathy (Coxsackievirus is one), this is a rare condition, and the average clinician may not see one in their lifetime. Since the common cold is so frequent it is very unlikely that this is going to occur to you. Of greater concern is your fear of this and if it persists you might want to see a mental health therapist. Best wishes ...Read more

Sudden death: Acls procedures for cpr, along with defibrillation, and antiarrhythmic drug initiation. After stabilizing, next goal is to determine whether the event was a primary arrythmia event or whether it occurred secondary to something else (heart attack, oxygenation, or electrolyte abnormality). ...Read more
Can sudden cardiac death from something like vfib happen to a healthy person and if so why? Anyway to prevent or detect it ahead if time?
Yes: Yes, sudden cardiac death can happen among healthy, active people. Certain conditions may cause it like anomaly in coronary artery or other genetic abnormality, or cardiomyopathy. Some conditions maybe suspected by a physician based on history, exam, EKG and echo of a patient. If a patient is identified to be at risk of sudden death an implantable defibrillator could save a life. ...Read more
LVH : Any degree of LVH remains a risk for arrhythmia and sudden cardiac death, although the risk is higher with degree of LVH, age and other cardiac risk factors. In one study, the risk of sudden cardiac death was 7%, particularly in the setting of atrial fibrillation. Treating hypertension, weight loss, alcohol cessation may reverse LVH and reduce risks of arrhythmia. ...Read more
