A Doppler fetal monitor, informally known as sonicaid (generic trademark), is a hand-held ultrasound transducer used to detect the fetal heartbeat for prenatal care. It uses the Doppler effect to provide an audible simulation of the heart beat. Some models also display the heart rate in beats per minute (BPM).
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.
Each Holter system has hardware (called monitor or recorder) for recording the signal, and software for review and analysis of the record. There may be a "patient button" on the front that the patient can press at specific instants such as feeling/being sick, going to bed, taking pills, marking an event of symptoms which is then documented in the symptoms diary, etc.; this records a mark that ...
A pregnancy test detects the presence of the pregnancy hormone human chorionic gonadotropin in a person’s body. The body doesn’t produce that hormone until several days after conception.
The atrioventricular block can be first degree or much more severe like a complete atrioventricular block (third degree). [5] [6] In addition, several changes in the ECG can be detected. [5] Other manifestations of the congenital heart block can be related to the impact of the maternal autoantibodies in the autoimmune-mediated CHB.
Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.
Today, a dedicated fetal echocardiogram can detect nearly 100% of serious congenital heart disease. Yet most pregnant women do not have a fetal echocardiogram but rather undergo a general obstetric ultrasound that may detect only around a third of fetal heart disease. To improve detection, some propose universal fetal echocardiography. [2]
Prenatal testing is a tool that can be used to detect some birth defects at various stages prior to birth. Prenatal testing consists of prenatal screening and prenatal diagnosis, which are aspects of prenatal care that focus on detecting problems with the pregnancy as early as possible. [1]
