A person’s normal heart rate can increase and decrease; variations between 50 and 60 beats per minute (bpm) are in the healthy range and do not require unusual attention. The term tachycardia is defined as a resting heart rate above 100 bpm, despite a resting state ranging between 80–100 bpm in general. If a person displays elevated heart rate during sleep, it may additionally be a symptom of hyperthyroidism or anemia. The wide variety of sensors can be multiplied up to eight. The hardware system consists of several components: a Bluetooth controller, a microcontroller, an ADC (analog to digital) converter, a signal conditioner, and a buzzer. The sensors are connected to the signal conditioner, through which all the values from the sensors are collected and then sent to the ADC. There, the signal is transformed from analog to digital and is then sent to the microcontroller which, transmits the data to the android software via a Bluetooth controller. In case of emergency, the buzzer will ring or an SMS/email will be dispatched to the health practitioner via their smartphone. All the data related to the patient are stored on the cloud server. We have brought cloud servers to the point where consumers of exclusive platforms can be interfaced with them, which overcomes the downside of using servlets.

HR is the number of heartbeats per unit time, which is commonly measured in minutes (bpm). The typical resting adult human heart rate is 60–100 beats per minute (bpm), according to the American Heart Association (AHA). When the heart rate increases beyond 100 beats per minute at rest, it is referred to as tachycardia, and when it falls below 60 beats per minute at rest, it is referred to as bradycardia (Fletcher et al., 2013). The HR was measured using three different approaches in the studies that were chosen. The first approach used ECG recordings (Engels et al., 1996; Engels & Wirth, 1997), whereas the second method employed a digital device attached to the participants’ left arm (Zaheri & Marandi, 2016) and in the third method, an HR monitor attached to the participant’s chest recorded the HR (Ping et al., 2011).

Pace mapping is a technique generally used to identify the site of origin of mostly focal ventricular, and sometimes for atrial tachycardias. A recorded electrocardiogram (ECG) during the clinical tachycardia is conventionally used as reference. Pace mapping is performed by visually or automatically comparing the QRS or P wave morphology during overdrive pacing to the recorded reference ECG [12,13]. Anatomic reconstruction of the atrium or ventricle is initially performed using a three-dimensional electroanatomical mapping system during sinus rhythm. Bipolar pace mapping is then systematically performed at the areas of interest based on the algorithm of QRS or P wave morphology of the tachycardia on surface ECG. Later, the expected area and surrounding area are paced, according to specific structure. If one of these areas obtains a good match of the QRS complex or P wave, denser pace mapping is performed close to the good-paced match site to obtain best-paced match site. The CA target of the tachycardia is defined as best-paced site [13].

Table 1 shows the frequency of main clinical symptoms occurrence in thallium salts poisoning among the patients under study. The earliest symptoms of thallium salts poisoning, which appeared in the first 24 hours after ingestion of toxic substances in the body, were gastrointestinal disorders. Among these, the most frequent were abdominal pain, mainly in epigastrium, less often in the perianal area - in 33 (84.6%) patients, nausea and/or vomiting - in 30 (76.9) patients, diarrhea - in 24 (61.5%) patients. It should be noted that two (5.1%) patients had gastrointestinal bleeding. Besides, there were symptoms of cardiovascular system disorder: tachycardia - in 36 (92.3%) patients, repolarization disorders - in 34 (87.2%) patients, while rhythm disorders and intracardiac conduction occurred less frequently. At the end of the first week after toxic substance ingestion, severe neurological disorders joined clinical symptomatology, namely, toxic encephalopathy in 100.0% of patients, disorders of consciousness (including 2 (5.1%) patients in coma), and delirium in 11 (28.2%) patients. The most recent were dermatological symptoms. Among them, the most frequent were alopecia and hyperpigmentation of the skin, which were present in all 39 (100.0%) patients.
