What are some signs of fibrillation?
rapid breathing
What are the vital signs of an anemic person?
If severe anaemia: tachycardia, orthostatic hypotension, tachypnoea
How will svt tachycardia affect a 26 year old white female?
In Caucasian females, especially those who are somewhat underweight, a common source of supra-ventricular tachycardia is MVP: Mitral Valve Prolapse. Although MVP is usually not dangerous, and can be controlled with medications designed to regulate heart rhythm, some rare cases of sudden death by ventricular fibrillation have occurred. Anyone with MVP should be under the care of a physician knowledgeable about the condition and its dangers. The patient should have EKGs on occasion, plus an echocardiogram (ECG) now and again to monitor things. If autoimmune disease is present, one should watch for any signs of acute myocarditis or chronic cardiomyopathy.If you have the insurance necessary to get in with a good cardiologist, it's worth it, but if not -- and many of us with chronic heart conditions don't -- at least keep up with your primary care physician. It's better than taking a risk otherwise.
Late signs of shock?
Tachycardia, weak pulse, hypo tension, dizziness, fainting, coma and death.
When should a health assessment be stopped-Absolute Indications Relative Indications?
# Suspicion of a myocardial infarction or acute myocardial infarction (heart attack) # Onset of moderate-to-severe angina (chest pain) # Drop in systolic blood pressure (SBP) below standing resting pressure or drop in SBP with increasing workload accompanied by signs or symptoms # Signs of poor perfusion (circulation or blood flow), including pallor (pale appearance to the skin), cyanosis (bluish discoloration), or cold and clammy skin # Severe or unusual shortness of breath # CNS (central nervous system) symptoms ## e.g., ataxia (failure of muscular coordination), vertigo (An illusion of dizzying movement), visual or gait (pattern of walking or running) problems, confusion) # Serious arrhythmias (abnormal heart rhythms) ## e.g.: second / third degree AV block, atrial fibrillation with fast ventricular response, increasing premature ventricular contractions or sustained ventricular tachycardia) # Technical inability to monitor the ECG # Patient's request (to stop) # Any chest pain that is increasing # Physical or verbal manifestations of shortness of breath of severe fatigue # Wheezing # Leg cramps or intermittent claudication (grade 3 on a 4-point scale) # Hypertensive response (SBP >260 mm Hg; DBP>115 mm Hg) # Pronounced ECG changes from baseline ## >2 mm of horizontal or down sloping ST- segment depression, or >2 mm of ST-segment elevation (except in aVR) # Exercise-induced bundle branch block that cannot be distinguished from ventricular tachycardia # Less serious arrhythmias (abnormal heart rhythms) such as supraventricular tachycardia
Ventricular tachycardia?
DefinitionVentricular tachycardia (VT) is a rapid heartbeat that starts in the ventricles.Alternative NamesWide-complex tachycardia; V tach; Tachycardia - ventricularCauses, incidence, and risk factorsVentricular tachycardia is a pulse rate of more than 100 beats per minute, with at least three irregular heartbeats in a row.The condition can develop as an early or late complication of a heart attack. It may also occur in patients with:CardiomyopathyHeart failureHeart surgeryMyocarditisValvular heart diseaseVentricular tachycardia can occur without heart disease.Scar tissue may form in the muscle of the ventricles days, months, or years after a heart attack. This can lead to ventricular tachycardia.Ventricular tachycardia can also be caused by:Anti-arrhythmic medicationsChanges in blood chemistry (such as a low potassium level)Changes in pH (acid-base)Lack of enough oxygen"Torsade de pointes" is a form of ventricular tachycardia that is often due to congenital heart disease or the use of certain medications.SymptomsIf the heart rate during a ventricular tachycardia episode is very fast or lasts longer than a few seconds. There may be symptoms such as:Chest discomfort (angina)Fainting(syncope)Light-headedness or dizzinessSensation of feeling the heart beat (palpitations)Shortness of breathNote: Symptoms may start and stop suddenly. In some cases, there are no symptoms.Signs and testsSigns include:Absent pulseLoss of consciousnessNormal or low blood pressureRapid pulseVentricular tachycardia may be seen on:Continuous ambulatory electrocardiogram (Holter monitor)ECGIntracardiac electrophysiology study(EPS)Loop recorderBlood chemistries and other tests may be done.TreatmentTreatment depends on the symptoms, and the type of heart disorder. Some people may not need treatment.If ventricular tachycardia becomes an emergency situation, it may require:CPRElectrical defibrillation or cardioversion (electric shock)Anti-arrhythmic medications (such as lidocaine, procainamide, sotalol, or amiodarone) given through a veinLong-term treatment of ventricular tachycardia may require the use of oral anti-arrhythmic medications (such as procainamide, amiodarone, or sotalol). However, anti-arrhythmic medications may have severe side effects. Their use is decreasing in favor of other treatments.Some ventricular tachycardias may be treated with an ablation procedure. Radiofrequency catheter ablation can cure certain tachycardias.A preferred treatment for many chronic (long-term) ventricular tachycardias consists of implanting a device called implantable cardioverter defibrillator (ICD). The ICD is usually implanted in the chest, like a pacemaker. It is connected to the heart with wires.The doctor programs the ICD to sense when ventricular tachycardia is occurring, and to administer a shock to stop it. The ICD may also be programmed to send a rapid burst of paced beats to interrupt the ventricular tachycardia. You may need to take anti-arrhythmic drugs to prevent repeated firing of the ICD.Expectations (prognosis)The outcome depends on the heart condition and symptoms.ComplicationsVentricular tachycardia may not cause symptoms in some people. However, it may be lethal in other people. It is a major cause of sudden cardiac death.Calling your health care providerGo to the emergency room or call the local emergency number (such as 911) if you have a rapid, irregular pulse, faint, or have chest pain. All of these may be signs of ventricular tachycardia.PreventionIn some cases, the disorder is not preventable. In other cases, it can be prevented by treating heart diseases and correcting blood chemistries.ReferencesOlgin JE, Zipes DP. Specific Arrhythmias: Diagnosis and Treatment.

You're treating a wounded Airman .You realize that he has probably lost approximately 2 liters of blood. What are the signs?
Pallor, diaphoresis, tachycardia, tachypnea, hypotension ...
Decreased cardiac output elevated left ventricular filling pressure peripheral vasoconstriction and arterial hypotension are all hallmark signs of what?

Why are the stop signs and the give way signs known as tha major signs in Kenya?
because they are madatory signs
When to use an AED?
Each AED is different. All new AED's self check themselves. Unless it beeps or flashes, it should be OK. Pads last from 2-3 years and batteries last 2-5 years. Check them at least once a month.
What are the signs of major back injury?
You can see the spine.
Why are the stop sign and give way sign known as the major signs in Kenya?
because they are mandatory signs
