This is crucial for earthquake warning system because P-waves
travel faster but S-waves cause more damage.
It was characterized by narrow complex tachycardia with regular RR interval and absence of p-waves
However, relatively strong P-wave
arrivals allowed to determine back azimuths directly from the P-waves
in this dataset.
D 2# Reflected channel wave, is formed by reflection of 1# reflection channel wave when encountering the tunnel face; E 3# reflected channel wave, is formed by the reflection of 2# reflection channel wave when encountering fault; F the roadway acoustic wave, is formed by the direct P-wave
when propagating into the cavity of the roadway; G the diffracted P-waves
at the endpoint of the tunnel face are the multiple diffractions when direct P-wave
encounters the endpoint (Kamsani et al.
of surface ECG were negative/positive in the inferior limb leads [Figure 1]a, and positive in V1.
His ECG showed discordance between p-waves
and QRS-complex; atrial heart rate was 100bpm (p-waves
) & ventricular rate was 26bpm (QRS-complex) [Figure 2].
It is characterized by unchanged PR intervals for conducted beats (those followed by a QRS), with intermittent sinus P-waves
without conduction through to the ventricles (evidenced by the absence of a QRS complex) (Surawicz & Knilans, 2008).
The arrival-time data of p-waves
from local earthquakes that occurred within the Kalabagh seismic network operated from March 1981 to September 1990 are used for inversion.
In third-degree IAB, there are longer P-waves
with biphasic morphology in the inferior leads.
The current patented sensing technology; NETQUAKEGUARD detects P-waves
(the non-destructive primary earthquake waves) in advance of damaging S and R waves.
In the photo-detachment process, these detached-electron p-waves
originate from each coherent source and interact with one another at large distance and on the observation plane we observe interferences .
