In order to be able to describe these complexes, a nomenclature for the waves is needed. The QRS complex is very important when diagnosing myocardial infarction. However, these waves can vary immensely in size, and arrangement. All sharp deflections resulting from electrical activation of the ventricles are called QRS complexes. The QRS complex of waves is the largest deflection of the ECG and is always spiky in shape. QRS waveform nomenclature The ECG consists of a small deflection called the P wave, arising from the atria, a more complicated deflection called the QRS complex due to ventricular depolarisation and a final T wave resulting from repolarisation of the ventricles. Segmento QRS: Despolarización de los ventrículos. Intervalo PR: Retardo del impulso en el nodo auriculoventricular. Onda P: Despolarización de las aurículas.

The mean pretest score was 61% and posttest score was 83%.Ĭonclusions: Our survey demonstrated that the burden of disease from overdose, substance abuse, and chronic ingestions in this area is exceedingly high and underappreciated. Nineteen emergency medicine residents at Cabral Hospital and fifteen family medicine residents at Juan XXIII Hospital completed the toxicology course. For the category of questions regarding basic toxicological awareness, community members answered 44%, medical students answered 61%, and medical residents answered 73% of the questions correctly. 6 (3%) use prescription pain medication daily. 32 (18%) practice home remedies that are potentially dangerous. 16 survey responders (9%) were exposed to toxic substances in the past and sought medical treatment. Results: 175 surveys were distributed: 134 community individuals, 22 medical residents, and 19 medical students. The curriculum was made available online through the Global Educational Toxicology Uniting Project (GETUP), supported by the American College of Medical Toxicology. A 72-page curriculum and a 12-item pretest and posttest was given to the medical residents enrolled in the course. Survey respondents were either 1) patients in the waiting room areas of the emergency departments and family medicine clinics at the Juan XXIII or Cabral Hospitals, which are both public hospitals 2) community members participating in a basic responder training course held at Juan XIII 3) medical students enrolled in Pontificia Universidad Católica Madre y Maestra (PUCMMM) medical school in Santiago 4) family medicine residents at Juan XXIII hospital 5) emergency medicine residents at Cabral Hospital. Methods: An 89-item survey was distributed and consisted of the following sections: demographics, previous toxicological exposures and medical encounters, storage and disposal practices of potential household toxins, traditional remedy practices, alcohol use, prescription pain medication use, and illicit substance abuse. To design and implement a curriculum written in Spanish to teach core principles about the management of overdose patients for medical students, family medicine residents, and emergency medicine residents. Objectives: To assess the fund of knowledge of patients, medical students, and medical residents in Santiago regarding the impact of alcohol ingestion, substance abuse, and chronic ingestions on the burden of disease. Although the burden of disease from acute and chronic ingestions is high in the DR, there is no formal training in toxicology, no Poison Control Centers, and relatively little access to appropriate laboratory testing, antidote administration, and specialty referral centers.
