are apical and radial pulses the same?
3281
Normally, these two readings should be the same. If there is a difference, it is called the pulse deficit. NOTE: An apical pulse will never be lower than the radial pulse.

['QRS duration is greater than or equal to 120 milliseconds.', 'In lead V1 and V2, there is an RSR` in leads V1 and V2.', 'In Leads 1 and V6, the S wave is of greater duration than the R wave, or the S wave is greater than 40 milliseconds.']

Typically, apical pulse rate is taken for a full minute to ensure accuracy; this is particularly important in infants and children due to the possible presence of sinus arrhythmia. Upon auscultating the apical pulse, you will hear the sounds “lub dup” – this counts as one beat.

P wave: 80 milliseconds. PR interval: 120-200 milliseconds. PR segment: 50-120 milliseconds. QRS complex: 80-100 milliseconds.

The P wave following the PVC is the sinus P wave, but the PR interval is too short for it to have caused the next QRS. (Remember, the PR interval following an interpolated PVC is usually longer than normal, not shorter!).

['Local - numbs one small area of the body. You stay awake and alert.', 'Regional - blocks pain in an area of the body, such an arm or leg. A common type is epidural anesthesia, which is often used during childbirth.', 'General - makes you unconscious.']

If the P wave is inverted, it is most likely an ectopic atrial rhythm not originating from the sinus node. Altered P wave morphology is seen in left or right atrial enlargement. The PTa segment can be used to diagnose pericarditis or atrial infarction.

A pulse refers to a disturbance that travel from one location to another location through a medium. While, A wave refers to the disturbance or variation that travels through the medium.

['Right axis deviation of +110° or more.', 'Dominant R wave in V1 (> 7mm tall or R/S ratio > 1).', 'Dominant S wave in V5 or V6 (> 7mm deep or R/S ratio < 1).', 'QRS duration < 120ms (i.e. changes not due to RBBB).']

The pulse is readily distinguished at the following locations: (1) at the point in the wrist where the radial artery approaches the surface; (2) at the side of the lower jaw where the external maxillary (facial) artery crosses it; (3) at the temple above and to the outer side of the eye, where the temporal artery is ...

In second-degree atrioventricular nodal block — also known as Wenckebach block or Mobitz Type I AV block — varying failure of conduction through the AV node occurs, such that some P waves may not be followed by a QRS complex. Unlike first-degree AV nodal block, a 1:1 P-wave-to-QRS-complex ratio is not maintained.

Q: Having trouble differentiating between Mobitz II and third-degree block. A: The main difference is this: Mobitz II: There will be a P-wave with every QRS. There may not always be a QRS complex with every p-wave.

The carotid is the preferred pulse point used during resuscitation of adults. In the lower extremities, the commonly evaluated pulses are the femoral, posterior tibial, dorsalis pedis, and sometimes the popliteal.

Angular frequency (ω), also known as radial or circular frequency, measures angular displacement per unit time. Its units are therefore degrees (or radians) per second. Hence, 1 Hz ≈ 6.28 rad/sec. Since 2π radians = 360°, 1 radian ≈ 57.3°.

Definition of Absent Peripheral Pulse Absence of peripheral pulses at baseline was defined as absence at palpation of at least one left- or right-side dorsalis pedis or posterior tibial pulse.

SA node (sinoatrial node) – known as the heart's natural pacemaker. The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles.

Measuring the apical pulse The doctor will place a stethoscope on the left side of the breastbone, over the apex of the heart. They can also feel the apical pulse at the point of maximal impulse (PMI). The PMI is in the space between the fifth and sixth ribs on the left side of the body.
