It adopts a simplistic fill-in-the-blank style [2] and is suited for medical students and junior residents. [1] The book was written by Dale Dubin , M.D. , a plastic surgeon and convicted felon, [ 3 ] who has written several books on cardiology including Ion Adventure in the Heartland: Exploring the Heart's Ionic-Molecular Microcosm [ 4 ] and ...
[6] [7] [8] He was sentenced to five years in prison [8] and his Florida medical license was revoked. [1] Dubin served three years and was released in December 1989. [9] In addition to his medical work, Dubin was for a time an avid hibiscus grower; a variety ("Dragon's Breath") he developed won Hibiscus of the Year in 1999. Dubin owns a patent ...
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [5] using electrodes placed on the skin.
Willem Einthoven was born in Semarang on Java in the Dutch East Indies (now Indonesia), the son of Louise Marie Mathilde Caroline de Vogel and Jacob Einthoven. [2] His father, a doctor, died when Willem was a child.
The most common causes of first-degree heart block are AV nodal disease, enhanced vagal tone (for example in athletes), myocarditis, acute myocardial infarction (especially acute inferior MI), electrolyte disturbances and medication. The medications that most commonly cause first-degree heart block are those that increase the refractory time of ...
First-degree AV block occurs when there is a delay, but not disruption, as the electrical signal moves between the atrium and the ventricles through the AV node. [3] On ECG, this is defined by a PR interval greater than 200 msec. Additionally, there are no dropped, or skipped, beats. [1] [4]
The 2018 European Society of Cardiology/American College of Cardiology Foundation/American Heart Association/World Health Federation Universal Definition of Myocardial Infarction for the ECG diagnosis of the ST segment elevation type of acute myocardial infarction require new ST elevation at J point of at least 1mm (0.1 mV) in two contiguous leads with the cut-points: ≥1 mm in all leads ...
The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. [1] It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, following a period of robust contraction and pumping of blood, called systole. [1]
