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
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.
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.

A fairly accurate estimate of the target heart rate, based on extensive clinical research, can be estimated by the formula 220 beats per minute minus patient's age. This linear relation is accurate up to about age 30, after which it mildly underestimates typical maximum attainable heart rates achievable by healthy individuals.
Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity to assess a patient's condition relative to their cardiac rhythm.Cardiac monitoring is usually carried out using electrocardiography, which is a noninvasive process that records the heart's electrical activity and displays it in an electrocardiogram.

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).
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.
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]
