What Should You Do When Someone Faints

Fainting happens when your brain doesn’t get enough blood, and that causes you to briefly lose consciousness.

What Causes Fainting:

Hyperventilation

Low blood sugar.

Being pregnant

Having anemia.

Emotional stress.

How to Diagnose VASOVAGAL SYNCOPE

How to Tell If Someone May Faint: *The patient says they feel nauseous. * Yawning frequently

* Feelings of restless

* Complaints of feeling lightheaded or dizzy

* The skin looks pale, feels cool and may be clammy or sweaty

* Complaining of tightness in the chest

* Having palpitations

A-FIB VERSUS JUNCTIONAL RHYTHMS

. ATRIAL FIBRILLATION: On your rhythm strip, the two most important characteristics are: . 1) A rhythm that’s IRREGULARLY irregular (meaning there’s no way to predict the next beat) 2) No discernible P waves . In fact, if you notice an irregularly irregular rhythm and you’re having to convince yourself that you see P waves... it’s probably A-fib (multifocal atrial arrhythmias like WAP/MAT could fit the differential) . *In my opinion: Don’t get caught up in using fibrillation waves as an absolute criteria. Very fine A-fib can sometimes produce a near isoelectric line between beats. . JUNCTIONAL RHYTHMS: The pacemaker cells surrounding the AV junction are capable of initiating regular impulses but at a slightly slower natural rate than their sinus and atrial superiors. The heart is built this way so that when the pacemaker cells with the fastest intrinsic rates are in action, those below are suppressed and function primarily to pass along the impulse from above. . For these reasons, we s...

The Pathway of Blood

Here’s a great illustration on the pathway of blood flow through the heart. It may seem easy...but you should know this cold as well as the cardiac anatomy, both of which will make procedures and understanding hemodynamics easier. . . . 💙VENOUS BLOOD- Blood flows into the heart (into the right atrium) through two major veins (the superior and inferior vena cava) as well as from the coronary sinus (cardiac venous blood from the coronaries) and then out through the first AV valve (tricuspid valve) into the right ventricle. From there blood flows into the right ventricular outflow tract, across the first semilunar valve (pulmonic valve) and into the main and then left and right pulmonary arteries. Blood then enters the lungs to become oxygenated. . . . ❤️ARTERIAL BLOOD- now that blood is oxygenated flow goes from the lungs into the left atrium through 4 veins (usually) called the pulmonary veins. From the left atrium blood flows across the other AV valve (mitral valve) and into the left ...

How to Stop Ectopic Beats

What is Ectopic Beats? According to Dr. Boon Lim - Ectopic beats are also known as Ectopic Heart Rhythm or cardiac ectopy. It is produced when the heart creates a premature beat, usually followed by a brief pause. Types of Ectopic Beats: 1. Premature Ventricular Contraction (PVC) 2. Premature Atrial Contraction (PAC) Causes Of Ectopic Beats There are different causes of Ectopic Beats. Some of these are Excessive alcohol consumption Excessive caffine consumptionPrescription drugs Stress (which produces high adrenaline levels) Exercise Diarrhoea and vomitting, which may disturb electrolyte levels (typically low potassium levels) Heart muscle damage from a heart attack Heart enlargement (cardiomyopathy) Valvular heart disease, such as a floppy mitral valve (mitral valve prolapse) Symptoms of Ectopic Beats Following Can Be The Symptom of Ectopic Beats: your heart is fluttering you are hyper aware of your heartbeat you feel faint or ...
