Essay about Vasovagal Syncope

An untrained 22-year-old male human subject was chosen. A PT-104 pulse plethysmograph was wrapped around his dominant (right) index finger. Connected through a IXTA data acquisition unit, heart rate was monitored on LabScribe. The recordings were measured with ten seconds of leeway at the beginning and end to allow baseline pulse recovery. Digital marks labeled the time interval of the described action. First the subject’s heart rate was measured during a resting phase for twenty seconds. He was encouraged to relax and remain inactive in order to confirm an accurate baseline reading. For the apneic condition, the subject repeated this

He doesn’t feel cold. That’s good, right? He isn’t in pain either. He’s still bleeding, which means his heart is still pumping. Pounding, in fact, a frantic tempo.

Decreases in blood volume:A decrease in blood volume can also cause blood pressure to drop. A significant loss of blood from major trauma, dehydration or severe internal bleeding reduces blood volume, leading to a severe drop in blood pressure, and Allergic reaction (anaphylaxis).When you get scarred a signal is triggered and is sent to the brain.The signal travels to the amygdala. The amygdala fires a brain chemical called glutamate out into two other regions of the brain. The first region makes us freeze or involuntarily jump. These reactions are so automatic because the signal is sent deep into the base of the brain to an area that we have little control over.The second signal is sent to the hypothalamus and triggers our autonomic nervous system — the system responsible for the fight or flight instinct. It elevates our heart rate and blood pressure and pumps adrenaline throughout our bodies.

One of my most vivid memories as a child includes my twin brother, the ledge at the bottom of our fireplace, and lots of blood (at least, what seemed like a lot of blood to my young brain). We were old enough to be left at home and not cause trouble—or so my parents thought—when my accident-prone brother decided to cartwheel straight into the fireplace, using his head as the target. With blood dripping down his forehead, and multiple failed attempts to call our parents, I could see the panic in my brother’s eyes, and I knew that I had to be calm and in control of the situation. After raiding our medicine cabinet and washing off as much blood as I could, I set to work bandaging my brother’s injury. From this experience I learned two things:

Though data from vagal stimulation was disregarded, it is still important to mention the responses that should have been elicited had the vagus nerve been stimulated properly. The vagus nerve (cranial nerve X) is a part of the parasympathetic nervous system and reduce heart rate when given enough electrical stimulation. Vagal escape occurs when the vagus nerve has been stimulated to the point of the nerve ceasing to repolarize, and then resuming sending action potential for heartbeat. The result is a cease or slowing of heart rate temporarily, and then heart rate starting up again. When atropine is applied to the heart along with vagal stimulation, the atropine blocks any response the vagus nerve should send (Sarnoff et al,

Cardiogenic shock is a life-threatening condition that requires immediate medical care. Treatment helps get blood flowing through your body again. Treatment may include:

then heart. The brain tells the heart to let go of more blood flow. Now in only one to five

“I see, so if we make him feel fear, then his heart rate will speed up. So if we make him calm, it will slow down, causing him to change back. He needs serious medical care urgently and will need to be delivered to the hospital.”

I now know that the hypotension is caused by vasodilatation because the sympathetic nerves that control tone are blocked. Peripheral

In this scenario, the subjected data is chest palpitation, lightheadedness and dizziness, the objective data is elevated heart rate with irregular rhythm, orthostatic blood pressure readings, lying 135/90, sitting 120/80, standing 100/60, and the client becoming dizzy and light-headed as he moves from a sitting to a standing position while taking the blood pressure. The subjective and objective data indicates that the patient has orthostatic hypotension. To determine what is causing the orthostatic hypotension a more in-depth health history, physical assessment, labs and diagnostic testing would need to be done.

Without early intervention on average 360,000 people out of the hospital succumb to cardiac arrest. “ Cardiac arrest and sudden death account for 60 percent of all deaths from coronary artery disease”,(Bledsoe, Porter, & Cherry, 2011,2007,2004, p. 1229)There are several causes of sudden cardiac arrest. Most are caused by ventricular fibrillation. “During ventricular fibrillation, the ventricles do not beat normally. Instead they quiver rapidly and irregularly.” When this occurs, the heart pumps very little and blood does not get circulated throughout the body. “ Most of the cases found with sudden cardiac death are related to undetected cardiovascular disease.("Sudden Cardiac Death," 2015, para. 2)Sudden cardiac arrest are immediate and drastic that includes sudden collapse, no pulse, not breathing, and loss of consciousness. “Four rhythms produce pulseless cardiac arrest: ventricular fibrillation, rapid ventricular tachycardia, pulseless electrical activity and asystole.”("Circulation ," 2005, p. IV-58)Other signs and symptoms that could occur prior to sudden cardiac arrest, include fatigue,

Mr Johan experiences symptoms of panic attack when he feels self-conscious in front of other people when performing certain tasks. He reported feeling faint and had black out of thoughts during those episodes, whereby he was not able to think of anything. Both his hands would tremble and become numb. He would also be sweating but experienced no symptoms of pounding heart or choking

Vasovagal is a term denoting the response caused through the stimulation of the Vagus nerve, which releases excess Acetylcholine; promoting the “relaxation response” (Dr Sircus 2014) triggering a series of events such as bradycardia and hypotension.

Vulvovaginal candidiasis is one of the most prevalent vaginal infections and represents, approximately 40%–50% of all cases of infectious vulvovaginitis [22]. The prevalence of RVVC among childbearing women and its importance as an Egyptian public health problem make an interest to continue research on such cases to add deep knowledge on RVVC and to understand the behavior of its pathogen and its epidemiology within Egyptian patients [23]. RVVC and its control by MBL was studied previously, but unfortunately none of the published papers discussed such cases in Egyptian patients. In an attempt to fill this gap, this study was designed on 118 childbearing Egyptian women to find out new therapeutic strategy for RVVC.

The woozy feeling when standing up too quickly. After going for a run, feeling as if one more beat and the heart would project itself out of the chest. Or quite the opposite and being in a very relaxed state. These are all changes one experiences at some time or another. What causes the different feelings and how each variable affects pulse rate and blood pressure has many wondering. Because of this curiosity, an experiment was performed to get some answers.
