Combining two sensor code in one sketch

Hello!
I’m trying to connect two sensors, a pulse sensor and a gyroscope in one sketch only, but every time i write the code, the printing numbers appear as null on the pulse sensor.
If anyone knows what’s wrong, it would be a great help

Gyro Code

#include "Wire.h" // This library allows you to communicate with I2C devices.
const int MPU_ADDR = 0x68; // I2C address of the MPU-6050. If AD0 pin is set to HIGH, the I2C address will be 0x69.

int16_t gyro_x // variables for gyro raw data

char tmp_str[7]; // temporary variable used in convert function
char* convert_int16_to_str(int16_t i) { // converts int16 to string. Moreover, resulting strings will have the same length in the debug monitor.
  sprintf(tmp_str, "%6d", i);
  return tmp_str;
}
void setup() {
  Serial.begin(9600);
  Wire.begin();
  Wire.beginTransmission(MPU_ADDR); // Begins a transmission to the I2C slave (GY-521 board)
  Wire.write(0x6B); // PWR_MGMT_1 register
  Wire.write(0); // set to zero (wakes up the MPU-6050)
  Wire.endTransmission(true);
}
void loop() {
  Wire.beginTransmission(MPU_ADDR);
  Wire.write(0x3B); // starting with register 0x3B (ACCEL_XOUT_H) [MPU-6000 and MPU-6050 Register Map and Descriptions Revision 4.2, p.40]
  Wire.endTransmission(false); // the parameter indicates that the Arduino will send a restart. As a result, the connection is kept active.
  Wire.requestFrom(MPU_ADDR, 7*2, true); // request a total of 7*2=14 registers
  
 
  gyro_x = Wire.read()<<8 | Wire.read(); // reading registers: 0x43 (GYRO_XOUT_H) and 0x44 (GYRO_XOUT_L)

  
 
  Serial.print(" | gX = "); Serial.print(convert_int16_to_str(gyro_x));

  Serial.println();
  
  // delay
  delay(9000);
}

Pulse Sensor code

#define USE_ARDUINO_INTERRUPTS true    
#include <PulseSensorPlayground.h>       

const int PulseWire = 0;       
int Threshold = 550;          
                                   
PulseSensorPlayground pulseSensor; 

void setup() {
   Serial.begin(9600);         
    pulseSensor.analogInput(PulseWire); 
    pulseSensor.setThreshold(Threshold);      
   
}
void loop() {
int myBPM = pulseSensor.getBeatsPerMinute();  
Serial.println(myBPM);                     
delay(500);
}

Gyro and Pulse

#define USE_ARDUINO_INTERRUPTS true    
#include <PulseSensorPlayground.h>  
#include "Wire.h" // This library allows you to communicate with I2C devices.
const int MPU_ADDR = 0x68; // I2C address of the MPU-6050. If AD0 pin is set to HIGH, the I2C address will be 0x69.
const int PulseWire = 0;       
int Threshold = 550;  
int16_t gyro_x; // variables for gyro raw data

PulseSensorPlayground pulseSensor;
char tmp_str[7]; // temporary variable used in convert function
char* convert_int16_to_str(int16_t i) { // converts int16 to string. Moreover, resulting strings will have the same length in the debug monitor.
  sprintf(tmp_str, "%6d", i);
  return tmp_str;
}
void setup() {
  Serial.begin(9600);
     pulseSensor.analogInput(PulseWire); 
    pulseSensor.setThreshold(Threshold);  
  Wire.begin();
  Wire.beginTransmission(MPU_ADDR); // Begins a transmission to the I2C slave (GY-521 board)
  Wire.write(0x6B); // PWR_MGMT_1 register
  Wire.write(0); // set to zero (wakes up the MPU-6050)
  Wire.endTransmission(true);   
}

void loop() {
  Wire.beginTransmission(MPU_ADDR);
  Wire.write(0x3B); // starting with register 0x3B (ACCEL_XOUT_H) [MPU-6000 and MPU-6050 Register Map and Descriptions Revision 4.2, p.40]
  Wire.endTransmission(false); // the parameter indicates that the Arduino will send a restart. As a result, the connection is kept active.
  Wire.requestFrom(MPU_ADDR, 7*2, true); // request a total of 7*2=14 registers
  gyro_x = Wire.read()<<8 | Wire.read(); // reading registers: 0x43 (GYRO_XOUT_H) and 0x44 (GYRO_XOUT_L)
  int myBPM = pulseSensor.getBeatsPerMinute();  
  Serial.println(myBPM);       
  Serial.print(" | gX = "); Serial.print(convert_int16_to_str(gyro_x));

  Serial.println();
  
  // delay
  delay(1000);
}

How many axis?

I going to guess its two.

Gates:
How many axis?

I going to guess its two.

It has 6 axis, but i only need the X.
THe problem rn is with the pulse sensor, since its the only that’s nos sending any info

const int PulseWire = 0;
pulseSensor.analogInput(PulseWire);

it looks like you are looking for an analog input on digital pin 0. what pin have you connected your pulse sensor to?

I've connected it to A0.
But now I've changed some code and its the gyroscope that's not working

I can't see the changed code so obviously I can't help with it.
