The penis becomes partially erect with a few seconds of erotic stimulation. Both the testes are drawn towards the perineum. The scrotum also becomes tense and thicken. Lasts from minutes to several hours. Then there is the swelling of the clitoris. The muscle that surrounds the vaginal opening becomes tighter. The vaginal walls also start to produce a lubricating the liquid. The breasts also increase in size and the nipples become hard. The rate and blood rate pressure increase. Breathing…

On a physical exam palpitations are a common symptom of AF often described as a rapid “fluttering in the chest,” with irregular “fluttering” that suggests AF, atrial flutter, or tachycardia with variable block.11 In patients with chronic atrial fibrillation, in-office exercise such as a brisk walk in the hallway may reveal an intermittent accelerated ventricular response as the cause of the palpitations.11 The clinician should look for signs of hyperthyroidism, or signs of stimulant drug use…

Migraines are a type of headache that is known as a "pounding" inside of your head. It has been proven that women who suffer from migraines have an increased risk on developing a cardiovascular disease later in life. Around one in five women suffer from migraines everyday, the pain varies on the person. However, if you are one of these people that experience migraines you are 39% higher to experience a heart attack. You are also 62% higher to have a stroke and 73% higher to have angina. Angina…

Introduction: Computed tomographic angiography (CTA) is recommended as a non-invasive test to determine the presence and severity of coronary artery disease (CAD). Aim of this study was to assess the accuracy of 256 slice CTA compared with invasive catheter angiography(ICA) in the diagnosis of significant CAD. Methodology: A prospective observational study in patients suspected of having CAD and undergoing both CTA and ICA for evaluation. Patients with coronary stents or surgical grafts were…

(2) Accelerated idioventricular rhythm An accelerated idioventricular rhythm is seen in as many as 20% of patients who have an AMI. This pattern is defined as a ventricular rhythm characterized by a wide QRS complex with a regular escape rate faster than the atrial rate, but less than 100 bpm. AV dissociation is frequent. Slow, nonconducted P waves are seen; these are unrelated to the fast, wide QRS rhythm. Most episodes are short and terminate spontaneously. They occur with equal frequency in…

and heart strain/chest pain which are some of the consequences of meth use. The reason for these symptoms is because meth is a powerful stimulant that can will speed up the heart while constricting blood vessels. The constriction of our patient’s arteries and veins resulted in intolerable chest pain and pressure. Vital signs such as temperature, pulse rate, blood pressure, and respiration rate were collected with the lab data. As for our patient, his heart rate and blood pressure where higher…

Even though complications of fistula access are far less than a graft or a catheter, they do occur and need to be addressed. Complications occur in approximately one-third of fistulas and include: aneurysms, infection, stenosis, thrombosis, steal syndrome and heart failure. These complications have historically been classified as early and late failure. The etiology of both early and late are somewhat similar because if the cause is not diagnosed early on it may progress and lead to late access…

Fetal Circulatory Routes Fetal circulation is the circulatory system of a fetus. This is also connected to the mother’s circulatory system. The mother’s body will do all the work that baby’s lungs will do once it is born. This circulation includes the umbilical cord and the blood vessels that are within the mother’s placenta. This carries the fetal blood. When the blood travels through the placenta it will pick up oxygen and become red. The blood will first go through the placenta, by then…

The mitral valve is a valve that allows blood flow from one chamber of the heart, the left atrium, to another called the left ventricle. In mitral valve prolapse, the valve slips backward due to the abnormal size of or damage to the mitral valve tissues. Mitral valve prolapse is a common cause of a heart murmur caused by a "leaky" heart valve. For most people with mitral valve prolapse, the cause is unknown. It can be caused by conditions in which cartilage is abnormal (connective tissue…

Left PROM lower extremity is limited in hip flexion 0-114, hip extension 5, hip abduction 35, and hip internal rotation 15, knee flexion 0-106, and hip external rotation 30. The lower extremity ankle dorsiflexion, ankle plantarflexion, ankle eversion, could not be assessed due to tone. Right lower extremity AROM was limited for hip extension 13, hip abduction 39, and ankle plantarflexion 62. Left lower extremity…
