is defined as a slow heartbeat rate, usually under 60 beats per minute in adults.
* If the infant has an apneic, bradycardic
, or oxygen desaturation event that requires stimulation, the infant is removed from the CSS immediately, and it is documented that the infant did not pass the challenge.
She was found to be bradycardic
with heart rates as low as 30 s.
At the arrival of the medical emergency team, the patient was comatose, anisocoric, bradycardic
, and hypotensive.
Telemetry monitoring did not show any additional bradycardic
episodes or sinus blocks.
Upon arrival, she was hypotensive (77/44 mm Hg), pale, bradycardic
, and febrile (39.4[degrees]C).
Once again she was found hypothermic (T: 33.0[degrees]C) and bradycardic
. She was treated empirically for urosepsis with IV tazocin, which was then switched to nitrofurantoin as blood tests did not suggest an infectious cause.
Soon after the steroids were started, the patient became hypertensive (180/114 mmHg) and bradycardic
with unbearable headaches prompting transfer to the pediatric intensive care unit.
On clinical examination, he was pale, bradycardic
(35 beats per minute), hypotensive (blood pressure: 60/40 mmHg), and tachypneic (26 breaths per minute).
Following the baseline BP and HR recordings, baroreflex sensitivity was evaluated by administration of phenylephrine (5 [micro]g[kg.sup.-1], i.v.) and sodium nitroprusside (30 [micro]g[kg.sup.-1], i.v.) by intravenous bolus injections to induce either an increase or decrease in BP, respectively, and subsequent bradycardic
or tachycardic responses.
(31) It has been reported that the injection of L-Arg into the RVLM elicited depressor and bradycardic
effects, while L-NAME increased blood pressure and [DELTA]HR.
events were most frequent and prolonged during sleep and when the patient was noncompliant with continuous positive airway pressure ventilation.
There, she was noted to be bradycardic
with a pulse rate in the 40's.
Three hours after administration of dexamethasone, he suddenly became apneic and bradycardic
with oxygen desaturation to 20% on HFOV with Fi[O.sub.2] 0.8, mean airway pressure (MAP) 11cm H2O, delta P 24, and frequency 14.5 Hz with inhaled nitric oxide 19 ppm.
Ketamine was chosen based on our previous experience and considering that alternative agents had either a long duration of action (pentobarbital), were potentially unsafe because of increased cardiac toxicity, or might cause a bradycardic
effect (isoflurane, ketamine/xylazine) as demonstrated elsewhere (Stein et al.
