Heartbeats

A heart murmur is when you hear a heartbeat that is not a continuous rhythm of beat, but instead you hear whooshing and swishing. This is caused by unstable blood in or near your heart. Your doctor can hear these sounds by using a stethoscope. You can get a heart murmur at birth or it can develop later in life. A heart murmur is not a disease but can affect the cardiovascular system which may lead to heart problems. Anyone from infant to adults can have a heart murmur. Infants and children may…

Children’s Museum Field Experience 1. “Seeing the Light” stained glass window display, located in the architectural section of the Children’s Museum, allows students to use the cling shapes to create their own stain glass window. A stain glass window would be an excellent form of visual art to use to teach geometric shapes and polygons. Samples of stain glass windows created from geometric shapes can be displayed on a projector for students to pick out squares, rhombuses, rectangles, triangles…

of planned parenthood. Pro-life politicians have been diligently working against the pro-choice politicians by pushing outrageous abortion laws such as the Heartbeat Bill. This bill states; It will be illegal for a woman to have an abortion after a fetus's heartbeat is detected under the assumption a fetus is a person after it has a heartbeat. This particular attempt has been shut down because John Kasich, the Republican governor of Ohio, vetoed the bill. This act, in turn, protected the…

It is clear that the novel’s narrator has a questionable mental state due to his weak grasp upon reality. This is seen in the way he attributes special powers to the old man’s eye and in his incomprehension towards neighbours hearing the final heartbeats of his victim. First of all, the narrator associates fictional powers with the old man’s pale blue eye. For example, after he had replaced all the floorboards “so cleverly” (Poe, p.8) he proceeds to explain that “no human eye-not even…

who aims to convince the reader of his sanity, while describing a murder he committed. Edgar Allan Poe demonstrates how a person’s inner turmoil and fear can drive him insane through an intricate plot, using symbols such as the old man’s eye, the heartbeat, and his own claim to sanity. To the narrator, the old man’s eye is a representation of something that the madman fears, and refuses to accept or confront. He uses…

Part 2: The Conduction System The conduction system of the heart works this way: Step 1: Pacemaker Impulse Generation. The SA node is known a natural pacemaker because it sets the pace of the heartbeat. It is where cardiac muscle contraction begin, from an impulse which causes the right and left atria to contract and push blood into the ventricles. Step 2: AV Node Impulse Conduction. From the atria, the electrical signal spreads to the AV node…

Premature Ventricular Contraction A premature ventricular contraction is an irregularity in the normal heart rhythm. These contractions are extra heartbeats that occur too early in the normal sequence. In most cases, these contractions are harmless and do not require treatment. CAUSES Premature ventricular contractions may occur without a known cause. In healthy people, the extra contractions may be caused by: • Smoking. • Drinking alcohol. • Caffeine. • Certain medicines. • Some…

The initial electrical impulse that begins the process of a heartbeat is generated by a group of cells located in the upper chamber of the heart. This special pathway is as follow: the sinoatrial node, atrioventricular node, his-purkinje network. The impulse starts in a small bundle of specialized cell which is known as the sinoatrial node located in the right atrium. The sinoatrial node sets the rate and rhythm of the heartbeat. The atrioventricular node slows the electrical signal before…

diagnose because there is a wide array of symptoms and it can be easily mistaken for other diseases. Most POTS patients experience dizziness, nausea, blurred vision, fainting, and fatigue. Since people’s heartbeats elevate when they stand up, POTS can either be diagnosed by taking the heartbeat standing up and sitting or doing a more complex Tilt-Table Test. Although anyone can develop POTS, it is most common in women of childbearing age. POTs can be hard to manage however, increased salt…

variation from the normal heartbeat. Heart rhythm disorders involve abnormalities of one or more of the following: heart rate, regularity of beats, sites where electrical impulses originate, or sequence of activation of heartbeats. Heart rhythm disorder is also referred to as an arrhythmia. The primary function of the heart is to supply blood and nutrients to the body. The regular beating, or contraction, of the heart moves the blood throughout the body. Each heartbeat is controlled by…
