What are the features of ECG?

ECG signal characteristics include frequency, time, morphology, energy, and RR interval [14]. Certain standard clinical ECG features and their combinations (e.g., amplitude and duration of P wave, QRS complex, T waves, etc.)

What is heartbeat classification?

The Association for Advancement of Medical Instrumentation (AAMI) categorized heartbeats into 5 classes: Normal(N), Supraventricular (S) ectopic, Ventricular (V) ectopic, Fusion (F) and Unknown (Q) beats [1]. Heartbeat classification is an essential step toward identifying arrhythmias.

What is the instrument of ECG?

An electrocardiogram (ECG) is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain spots on the chest, arms, and legs. The electrodes are connected to an ECG machine by lead wires.

How is ECG measured?

During an ECG , up to 12 sensors (electrodes) are attached to the chest and limbs. The electrodes are sticky patches with wires that connect to a monitor. They record the electrical signals that make the heart beat. A computer records the information and displays it as waves on a monitor or on paper.

What are the 3 types of arrhythmias?

Arrhythmias that cause a slow, fast, or irregular heartbeat
  • Bradycardia is a resting heart rate that is slower than 60 beats per minute. …
  • Tachycardia is a resting heart rate that is faster than 100 beats per minute. …
  • A premature or extra heartbeat happens when the signal to beat comes too early.

What is full form ECG?

An electrocardiogram (ECG) is a simple test that can be used to check your heart’s rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats.

What is heartbeat in biology?

Heartbeat is defined as rhythmic contraction and relaxation of heart muscles.This happens from birth till death. Heart rate is the number of heartbeats per minute.

What is a normal heart rate?

A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.

What is the highest heart beat?

You can estimate your maximum heart rate based on your age. To estimate your maximum age-related heart rate, subtract your age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 – 50 years = 170 beats per minute (bpm).

What heart rate is too high?

Tachycardia refers to a high resting heart rate. In adults, the heart usually beats between 60 and 100 times per minute. Doctors usually consider a heart rate of over 100 beats per minute to be too fast, though this varies among individuals.

What are the 7 vital signs?

What are vital signs?
  • Body temperature.
  • Pulse rate.
  • Respiration rate (rate of breathing)
  • Blood pressure (Blood pressure is not considered a vital sign, but is often measured along with the vital signs.)

What is normal pulse by age?

Normal Heart Rate by Age Chart
AgeNormal Resting Heart Rate
Children 5 to 6 years old75 to 115 bpm
Children 7 to 9 years old70 to 110 bpm
Children 10 years and older and adults (including seniors)60 to 100 bpm
Athletes in top condition40 to 60 bpm

What is normal spo2 and PR bpm?

An ideal oxygen level is between 96% and 99% and an ideal heart rate is between 50 and 90 beats per minute (bpm).

What are the 3 types of pulse?

Types of pulses

The pulse felt on the neck is called the carotid pulse. When felt on the groin, it is called the femoral pulse. The pulse at your wrist is called the radial pulse.

What are the 5 types of vital signs?

Vital Signs (Body Temperature, Pulse Rate, Respiration Rate, Blood Pressure)

Is 120 pulse rate normal?

A resting pulse rate of 120 BPM in adults would be considered high, while a heart rate between 60 beats per minute (BPM) and 100 BPM is normal for people 15 years and older. The pulse rate, also called your heart rate, is the number of times the heartbeats per minute (BPM).

What are the 7 pulse points?

The pulse points are the neck (carotid artery), the wrist (radial artery), behind the knee (popliteal artery), the groin (femoral artery), inside the elbow (brachial artery), the foot (dorsalis pedis and posterior tibial artery), the abdomen (abdominal aorta).

What are the 4 types of pulses?

Pulses are the dried seeds of legumes, and come in a many different shapes and sizes. This guide will show you a visual reference, description and common names for some of the varieties of the four most common pulses: beans, chickpeas, lentils and peas.

What are the 9 sites of pulse?

  • Radial artery. Radial side of wrist. …
  • Brachial artery. Medial border of humerus at elbow medial to biceps tendon. …
  • Carotid artery. Press examiner’s left thumb against patient’s larynx. …
  • Femoral artery. …
  • Popliteal artery. …
  • Dorsalis pedis (DP) and tibialis posterior (TP) arteries (foot) …
  • The abdominal aorta.

What are the 10 pulses?

The United Nations Food and Agriculture Organization (FAO) recognizes 11 types of pulses: dry beans, dry broad beans, dry peas, chickpeas, cow peas, pigeon peas, lentils, Bambara beans, vetches, lupins and pulses nes (not elsewhere specified – minor pulses that don’t fall into one of the other categories).

Why are 3 fingers used to check pulse?

This has a reason: the finger closest to the heart is used to occlude the pulse pressure, the middle finger is used get a crude estimate of the blood pressure, and the finger most distal to the heart (usually the ring finger) is used to nullify the effect of the ulnar pulse as the two arteries are connected via the …
