The neurotransmitters implicated in the control of nausea and vomiting include acetylcholine, dopamine, histamine (H1 receptor), substance P (NK-1 receptor), and serotonin (5-HT3 receptor). There are also opioid receptors present, which may be involved in the mechanism by which opiates cause nausea and vomiting.
Drug reaction (vomiting may occur as an acute somatic response to): [citation needed] Alcohol, which can be partially oxidized into acetaldehyde that causes the symptoms of hangover, including nausea, vomiting, shortness of breath, and fast heart rate. [22] Opioids; Selective serotonin reuptake inhibitors; Many chemotherapy drugs
It may be accompanied by symptoms such as salivation, feeling faint, and a fast heart rate. [7] Vomiting is the forceful ejection of stomach contents through the mouth. [7] Although nausea and vomiting are closely related, some patients experience one symptom without the other and it may be easier to eliminate vomiting than nausea. [1]
Some chemotherapeutic agents may not cause nausea and vomiting on their own, but may when used in combination with other agents. [6] Regimens that are linked to a high incidence (90% or higher) of nausea and vomiting are referred to as "highly emetogenic chemotherapy", and those causing a moderate incidence (30–90%) of nausea and vomiting are ...
Wearable technologies that monitor heart rate has interested users for a very long time. [14] In addition to the pulse watch which monitors heart rate from pulse detection at the wrist. There are also devices which use similar technologies to monitor heart rate from the ear, forearm and chest, using a chest strap. [2]
The 5-HT 3 receptor antagonists suppress vomiting and nausea by inhibiting serotonin binding to the 5-HT 3 receptors. The highest concentration of 5-HT 3 receptors in the central nervous system are found in the STN and chemoreceptor trigger zone (CTZ), and 5-HT 3 antagonists may also suppress vomiting and nausea by acting at these sites. [29]
The monitor showed his heart rate was at 164 beats per minute (bpm) at the start of his daughter’s routine. But his heart rate jumped up to 181 bpm as he continued to watch.
A heart rate monitor (HRM) is a personal monitoring device that allows one to measure/display heart rate in real time or record the heart rate for later study. It is largely used to gather heart rate data while performing various types of physical exercise. Measuring electrical heart information is referred to as electrocardiography (ECG or EKG).
