I am beginning to get a bit confused about sampling rates and baudrates etc. I have this Arduino code:

#include <eHealth.h>

extern volatile unsigned long timer0_overflow_count;
float fanalog0;
int analog0;
unsigned long time;


byte serialByte;
void setup() {
  Serial.begin(9600);
}

void loop() { 
  while (Serial.available()>0){  
    serialByte=Serial.read();
    if (serialByte=='S'){        
      while(1){
        fanalog0=eHealth.getECG();  
        // Use the timer0 => 1 tick every 4 us
        time=(timer0_overflow_count << 8) + TCNT0;        
        // Microseconds conversion.
        time=(time*4);   
        //Print in a file for simulation
        //Serial.print(time);
        //Serial.print(" ");
        Serial.print(fanalog0,5);
        Serial.print("\n");

        if (Serial.available()>0){
          serialByte=Serial.read();
          if (serialByte=='F')  break;
        }
      }
    }
  }
}

Since there is no delay interrupt, what is the sampling rate/frequency? Is it based on the Arduino ADC speed? When I increase the baudrate am I increasing the sampling frequency or just the rate at which I send data over the serial port?
